Cool game! Loved shooting stuff with my blaster :)
A few thoughts on how to improve it: I have escaped without doing a single jump - it was easier to just stand on initial platform and shoot incoming asteroids with rapid fire (they got 4 stones out ot 5, but defend one is even easier). It would be cool to be able to move vertically and reach the ship by yourself, not just waiting for it. I think it would add more choice between staying and trying to get more score and moving to escape (this choice is present in https://itch.io/jam/scorejam29/rate/2661422, but it lacks the right amount of danger).
The stats screen and abilities are very nice additions!
