A nice game, I got a webGL error in my browser (I think it was either when I collided with an asteroid or with the sun, not sure). The turning felt a bit unnatural but I got used to it over time. Maybe you could make the asteroids a bit faster but put fewer of them? It would make it much more chaotic and maybe a bit more fun too that way.
Wanna give my game a try too? https://itch.io/jam/brackeys-6/rate/1077360
