I think there is some bugs with pressing too many buttons at once and losing extra cubes per space. I lost on the first level, somehow had 1 too little. I think it would be cool if you could go back over the spaces you have already been and pick your cube back up, or perhaps leave more than one on a space and pick them back up later, and being smaller had some kind of benefit, that way you have a lot more flexibility for puzzles. What you have right now feels very much like just a “moves” limit, like you could have achieved the same effect with a counter at the top right. I like the idea of a character that morphs and changes as you play him, that’s a neat idea!
