I completely crashed a couple of times before I got it, but once I did it was pretty fun! I liked how the altitude was an impactful decision, since you couldn’t go too high. I did manage to save myself from a crazy fall though which was fun. Maybe add a score system for “tricks” like Sonic Adventure 2 Battle or Tony Hawk’s?
I think a few more “interactable” elements would be great. The clouds are fun, and it took me a few to notice it was actually a powerup. Perhaps adding birds, or even shooting stars like in Terraria? Overall good job!
