Hm, updates seem to work now. Not sure why they would not go through before. Anyway there is a new version now (v0.9 -- you can check on the help page) with many more rocks and a few minor fixes. Thank you for the feedback.
level 24 is almost impossible because the blue guys move slightly more than the red guys, took me about 20 resets to notice this... really annoying glitch, it's like being trolled by a game
hurts my ears when you have a ship with a decent magnet and pick everything up at once, you should have it play the pickup sound only once every frame or two instead of having a dozen instances of the sound effect playing at once
what's the deal with "bullet hell" games where your movement is severely limited? that really defeats the entire purpose of the genre. the point is that you can use your skill to react and dodge quickly, not buy enough upgrades to eat enough bullets to survive.
changing my vote from a 5 to a 1, it's really irritating that you start so zoomed in, it makes it impossible to get the later "ace" achievements considering you'll always smack into something invisible within the first 10k air units
