Great game! Honestly the complete package right here! The simple art is great, the animations and menus are really polished, the gameplay is fun and varied. I liked how creative some of the control schemes you made were, like the diagonal thrusters and reverse flappy bird especially. It also keeps the gameplay fresh and varied. The game isn't a pushover either, I had to come back and beat it on my second time (granted i was trying to learn the game on the first round and took a while to get used to each of the controls)
Only point of feedback is that sometimes it is impossible to get to an asteroid on some control schemes like the diagonal thruster, and this can get frustrating if these situations chain together multiple times due to bad luck. But I could just be unlucky, and it really isn't that big of a deal.
Overall an excellent game that accomplishes what it is trying to do very well! Great job!
