We debated adding an undo button but thought people would just brute force instead of really think their actions through, So we decided against it in the end.
I get even less this awnser.
you can still reset levels by pressing the reset button so the amount of actions you have to redo is relatively limited
Yeah, but the undo button is required for a good puzzle game. Try beating Baba Is You with no undo or Patrick's Parabox with no undo.
