really interesting idea !
i think a visual cue that you're now controlling the creature would help a lot, i thought my game froze or something
and i feel like the blocks were too sensitive to what's around them, i thought i aimed it well enough between other platforms, but then it just stopped on a corner way too high
not sure how this could be improved, but it definitely makes the game seem more unforgiving
really cute style and nice idea, good work with this !
