The idea of multiple purchasable modes is actually pretty awesome, maybe you could buy these in the form of modifiers that can be switched on and off, so you can mess around with multiple of them at the same time
this game's cool, I will say, the later levels get pretty annoying, I couldn't get past that level where you follow the text's instructions on that long invisible path, but I still think this is a pretty neat game! honestly I've even been considering making a fangame, if that's fine with you
