This game is pretty fun!
I like the idea, I wasn't expecting the player to literally be earth lol.
The game looks very good! It would have been greatly improved by adding some cloud variants to the sky, but it's still great to look at!
The game in itself is fun, I like having to anticipate the moves of the planet, but the last level is very difficult, you gain speed extremely quickly, and once you're too fast you pass through blocks or get stuck inside. I think you should maybe have a max speed so that it doesn't break the physics.
I had a lot of fun with this one! It's a great way to play, and using a rolling ball makes the game more interesting!
