Third iteration of penisdraw! By me this time.
Server usage: love . --server [--address <ip address>] [--port <port>] to host. You can host a server running main.lua with Lua 5.1 or LuaJIT, as long as you have lua-enet installed. Server also requires lua-lgi, cairo, gir1.2-freedesktop.
Client usage: love . --address <ip address> [--port <port>] to connect. Click and drag to draw!
