I've always had a soft spot for these types of 'incremental' games. Great choice allowing the player to just hold down the button. I don't know if I would have survived pressing the spacebar a thousand times haha.
Controls were really responsive and tight. I love the minimalistic look of the game as well! I had the same issue as Kisame on Level 5 where I softlocked my progress by grabbing a key and then dying after pressing the switch.
I like the story, it's very funny. I think an improvement would be preserving the forward momentum when you do the jump though - and then allowing the player to 'cancel' it if they want by pressing again mid-air to go backwards. I felt it would have been a lot smoother if the player was able to jump forwards, but that's just my opinion.
Simple and easy to understand. I think a good improvement would be to have the asteroids spawn outside the screen, but having them spawn close was a good challenge! I couldn't hear any audio for the game though.
