I really like the concept, it is a really original compare to other game out there. It is also very fun and I would see it being a full fledged html 5 game on itch. My only grip with it is the control feel a bit to tight because there is no acceleration in the movement especially with air control.
As for the rest, the visual is serviceable, but good. SFX and music are well placed (laugh a bit at the victory music). There was no bug found during play through (outside of the issue with the full screen). Tutorial was well placed.
So overall, it was a pretty good game. Good Job :)
