This was great! So many little details add to the experience.
I love how you use sounds to suggest unseen elements.
The fact that the level geometry is usually curved, rather than square, really helps players to make an informed guess from the small amount they can see. Really nice touch.
I kind of felt like I was flying an egg, which makes me wonder how this would look with big egg yolks in the splats :D
My only complaint is that I think I have RSI now... Maybe let players use the spacebar for upward thrust as well, so there's an option to spread those inputs out?
This game really deserves more ratings. I think you're still allowed to upload a WebGL build, so long as you don't modify the game.
