What you make is up to you! Personally I myself was inspired by games like Crypt of the Necrodancer/Ending when I was making this game, but I tried to differentiate the mechanics/aesthetic in order to give it its own distinct identity. Best of luck!
Haha yeah I could tell there was some necrodancer inspiration in there! Personally I wanted to make a version where the weapon switching mechanic you put in is tied to everything, instead of switching the weapon I was thinking of switching the color of the enemies and all interactables every 3 moves the player makes.
