i don't see how it uses the limitation? the jam's limitation was "Constant Motion" and your use of limitation field talks about using only one button. the game also crashed for me as soon as i entered level 2
Sorry for the inconvenience. Because the limit is "Constant Motion", so all objects in the game only move in one direction which refers to the character itself moving in one direction or one button. That's what I can get CMIIW
