Not bad! If there are 4 players, you might wanna split the buttons further away instead of packing them into QWER four in a row.
Thanks! You are absolutely correct about the buttons, they should be different! When I tried changing them to something more reasonable (like q, z, p, m), it broke, but if you'd like to investigate, the player keycodes are stored in "plr_keys"!
I tried changing it to Q,Z,P,M in the main.lua and it worked.
lolol, it looks like my version is cursed
