Cool concept! Enjoyed trying it out. I think the music for this was really nice, and fit the vibe quite well!
I'd say gameplay wise, Maybe some incentives to speed up deliveries would make the game a bit more exciting? Right now it seems that the best strategy is to be patient with the asteroids, which is not particularly fun, so it would be cool if you were rewarded for taking riskier routes. Also there could be a lot of opportunity for progression (upgrades, etc!) in future, if you were work on this game further!
For for now it does look pretty neat! Thanks for taking part in the jam!
