I like the idea of an incremental lewd game with this premise, but the gameplay itself is way too tedious for what it is. Having to wait until the ball is completely done rolling to shoot it again is annoying, and each run takes too long for what little improvement you can get after a run. Also, there's very little incentive to go to further screens. As far as I've seen, asteroid health directly scales with asteroid value, so getting tougher asteroids doesn't actually improve your health-to-stardust ratio or your speed of breaking asteroids. And not breaking an asteroid you damaged, something that's more common on farther levels) is a waste of health
There's a lot of ways this could be improved upon, if you put some time into redesigning how things worked to be faster and snappier, so you can actually feel yourself improving in power as you play.
