I got to the ending! The game has charming visuals and a simple but effective gameplay.
Some feedback: I think either the glider should activate automatically after 20 boxes, or it should be activated with just a button press, or it should have some kind of visual indicator. I was also unsure if getting hit would reset the 3 seconds counter. Also, this game could really use some sound effects.
The UI is lovely and so is the background. The game has solid visual consistency and despite being difficult to beat, it's very easy to pick up and play. Good job!
