I recognized the graphics and realized it was from DavidA3D from the first M-A-L game jam. Hey man! 😄
Anyway, the game was a bit difficult for me, so I didn't get to finish it yet. Maybe I'll try again another time because I like a challenge.
On the other hand, the flying feature really shined here and was wondering if you could try and add flight direction control via WASD, and possibly consider a double jump that activates the flying mode.
