took a second for me to figure out how everything works but its a neat game!
(btw if you havent figured it out yet, for colors in Gamemaker, both $FFFFFF and #FFFFFF work but $ is in blue/green/red order while # is in red/green/blue order, so if you use #A1A100 or $00A1A1 it should be correct but $A1A100 would be wrong)
