That was cute.
I definitely lacked the ability to regulate "breathing" in flight or movement.
Game control also needs to be improved. I played with one hand (wsad) and it was not convenient for me to skip text on (с) and change the "breath" through (x) and (z). Space, Shift and Control would be better for me :)
There are some bugs. For example, you can stand on the very edge of a platform with spikes and it won't kill you.
Overall, I got a full game experience, with a cute character visual style and even some challenge. Good luck.
