The point balloon floats in the game space like a balloon, and the point of the balloon can be obtained by contact with a part of a human-powered airplane.

Each game stage A, B, C of this embodiment
Is composed of three game stages for each of the difficulty levels of beginner, intermediate and advanced. These three game stages of beginner level, intermediate level, and advanced level are each configured as the same game space, and are set so that only the difficulty level is different. The elementary, intermediate, and advanced game stages having different degrees of difficulty are configured so that the point balloons are arranged and the number of points in the game space is different.

For example, a beginner level game stage having the lowest difficulty level is configured so that a beginner can play and clear it at the last minute. In particular,
The point balloons are located in a relatively easy-to-take and easy-to-find position so that even beginners can acquire the minimum required points to clear the stage within the time limit. The intermediate game stage is designed so that you cannot complete it without challenging difficult points. Specifically, point balloons are installed near obstacles and so that they cannot be removed simply by flying straight. In the advanced game stage, point balloons are placed so that you can clear the points if you do not know the terrain of the game space and challenge fairly difficult points.

For example, taking the game stage A as an example,
Beginner, Intermediate, and Advanced game stages A1, A2, A3
2 are configured by using the same game space 300 shown in FIG. 2, and the respective difficulty levels are set by the arrangement of the point balloons in this game space.

Elementary, Intermediate,
The advanced game stages B1, B2, and B3 are also included in the game stage C, and are the beginner, intermediate, and advanced game stages C.
1, C2 and C3 are similarly configured. However, the final game stage D is configured as a game stage of one difficulty level.

The game device of the embodiment can start the game from any of the game stages A, B and C, and the player clears each stage and selects the remaining stage to continue the game. Each time the game is played, the difficulty level of the game is gradually increased. For example, when the player first selects the game stage A, the difficulty level thereof is set to the beginner level, and the game is played on the first game stage A1.

When this game stage A1 is cleared,
The player can select one of the remaining B and C game stages. For example, when the game stage B is selected, the game on the intermediate level game stage B2 is automatically continued.

When this game stage B2 is cleared, the remaining game stage is only C, so that the game level C of the advanced level with the highest difficulty level is automatically set.
The game at 3 will continue.

In this way, no matter which game stage the player starts the game, the first stage is the beginner level,
The next stage will be intermediate and the third stage will be advanced, and the difficulty level of the game stage will gradually increase. When all of the selectable game stages A, B and C are cleared, the final game stage D is automatically selected and the game on this game stage D is played.

FIG. 5 shows a functional block diagram of the game apparatus of the embodiment.

In this embodiment, when the player starts the game from the beginning, all the game stages A, B, and C are set as selectable game stages and displayed on the display 30. The player selects from the displayed selectable game stages A, B, C
An arbitrary game stage is selected by the stage selection unit 28 to start the game. When the player clears the game stage, the remaining stages of the three game stages A, B, and C except the stages already cleared by the player are set as selectable stages for continuing the game. , This is displayed on the display 30. For example, when the player clears only the game stage A, the remaining game stages B and C are displayed on the display 30 as selectable game stages. The stage selection is performed using the stage selection unit 28.

All game stages A, B, C
When is cleared, the final game stage D is automatically set as a stage for continuing the game.

The difficulty level setting section 150 is formed so that the difficulty level of the newly selected game stage is gradually increased each time one of the game stages A, B and C is cleared. That is, after the game starts, the difficulty level of the first selected game stage is beginner,
The difficulty level of the next selected game stage after this game stage is cleared is automatically set to intermediate level, and the difficulty level of the next selected game stage after this intermediate game stage is cleared is automatically set to advanced level.

The continue acceptance section 160 displays the continue acceptance screen on the display 30 for a predetermined time when the game stage is not cleared based on the detection signal of the clear determination section 130. Only when the player selects the continue from the continue input unit 29 within this time, the arithmetic control unit 100 is instructed to start the game on the game stage that the player cannot clear from the beginning with the same difficulty level. To output. In addition, when continue is not selected within the reception time, the game is automatically controlled to be over.

FIG. 6 shows an operation flowchart of the game apparatus of this embodiment, and FIG. 7 shows a game stage selection flow.

= 1 is automatically set to the beginner level (step S10), and a selection message for the game stage of A, B, C is output on the display. Here, the player
When an arbitrary stage is selected from the B and C stages (step S12), the game on the selected stage is played (step S14).

In the selection of the first game stage, as shown in FIG. 7, no matter which game stage is selected, the difficulty level of the game stage is set to the beginner level.

Then, when a predetermined time limit has elapsed since the game started, or when the reference points are cleared within this time limit, the game at the relevant game stage ends and the game result is displayed on the display 30. Is displayed (step S16), and it is determined whether or not the stage has been cleared (step S18).

When the first game stage is cleared, the difficulty level is then incremented by 1, the difficulty level is set to the intermediate level (step S24), and the next selectable game stage is determined (step S26). ).

For example, when the game stage A is first selected, the game stages B and C are displayed on the display 30 as selectable stages. When the player selects an arbitrary stage from these game stages B and C, the game at the next game stage is played as a game having an intermediate level of difficulty as shown in FIG. The result is displayed (steps S14 and S16). For example, when the game stage B is selected (step S12), a game is played on the game stage B2 having an intermediate difficulty level, and the game result is displayed after the game ends (steps S14, 1).
6).

When it is determined that this game stage has been cleared (step S18), the difficulty level is set to the advanced level in the same manner as described above (step S24).
Of the B and C game stages, the remaining game stages that have not been cleared by the player are determined as the next selectable game stage, and the player is allowed to make that selection (steps S26, 12). Since there is only one remaining game stage here, this game stage is automatically set as the next continuing game. For example, if you clear the stages A and B and have not cleared C yet,
Is automatically set as the advanced level game stage, and the game is played on the advanced game stage C3 (steps S26, S12, S14).

After the game is over, the game result at that game stage is displayed (step S16), and when this game stage is cleared (step S1).
8) Then, the determination in step S22 is performed. In this step S22, it is determined whether or not all the game stages A, B and C have been cleared. Since A, B, and C are all cleared here, the ending stage D is automatically selected next (step S28), and the game on stage D is played (step S14).

After the game is over, the game result is displayed (step S16). Then, when the ending game stage D is cleared (step S20), the total score on all the game stages A to D is displayed (step S30), and the game is over.

In this way, with the game device according to this embodiment, the player can play while arbitrarily selecting the game stage, and the difficulty level of each time the player clears the selected game stage. Level up automatically.

At this time, in order to clear the difficult game stage, the player is required to have a considerable game technique. And all game stages A,
Only those who clear B and C can challenge the final game stage D for ending, and only those who clear this ending game stage D can acquire items that save humanity.

Therefore, since the player challenges each game stage with a sense of tension, it is possible to realize an interesting game full of tension.

Further, since the player can start the game from any of the game stages A, B and C, even the player who cannot clear the first game stage can change the stage to be challenged each time. A game can be played while enjoying all the game effects of the three game stages A, B, and C.

As described above, according to the present invention, it is possible to realize a game device that allows beginners to advanced players to enjoy an interesting game while fully enjoying the game effect on each game stage. .

Further, in the game device of this embodiment, when the game stage in the middle cannot be cleared (step S
18), the continue screen is displayed on the display (step S40), and the player is given another opportunity to challenge the game stage again (step S40). At this time, if the continue is not selected, the game is over (step S42), but if the continue is selected, the same game stage is automatically set to the same difficulty level (steps S42, S44).
The game on that stage can be continued as a continue game from the beginning (steps S14 and S16).

This continue game is repeated as many times as long as the player selects the continue if the player cannot clear the game stage. As a result, a player who can never clear the beginner's stage understands the scenery of the game space that configures the stage and the arrangement of point balloons by repeating the game on that stage as many times as a continue game, You can devise a way to capture point balloons. Therefore, by challenging the continue game several times, the player sequentially clears each game stage, and the final game stage D
Can be reached.
