I do understand how simplifying the controls to one button would help, as when starting to make the game I pressed the wrong button more than a few times. However, I kept it as two buttons as the 'Purple Area' mechanic does act differently depending on what button you press, and I felt that the player should use this mechanic to have more options on approach in the later levels (such as the large purple area in levels 8 and 10). I tried to put a control scheme that uses the arrow keys, which may be a bit more intuitive, even though it does just remap directly to the same actions as X and Z. Thanks for playing it!
