something that could improve the art is stop ussing mirrored sprites, and change the engine like that one guiy there said
the engine isnt that bad, im sure u can do an exact replica of the pizza tower moveset in there.
u can do that even in construct 2.
i mean things the collision, movement, and some things in art too, like: use less mirrored sprites, and theres lots of unproportions between the sprites
