This was cool! I was able to get pretty far without needing to move much at all hahaha. I wonder if, instead of having the asteroids be totally random, there's a guarantee that every like 4-8 asteroids (chosen randomly) spawn on the lane you're currently on, just to make sure there aren't any long stretches of time where the player doesn't have to move. Otherwise I really liked this though, the visuals felt really polished for a PICO-8 game and the music was nice too. Great job!
