Excellent sound design and it gives a really chill vibe as you play! I think it might be a bit slow to get upgrades and progress, but I can see how you could get to a point where your asteroid is just demolishing whole screens. It's satisfying but just a bit slow to get started. I think if you could interrupt the roll of your character, or if there was a bit more bounciness when you hit things would add to the speed of the game.
The character is super cute as well, nice work!
