Fantastic vibes (it was like playing a screensaver or somethin), clever central mechanic, and satisfying powerups. The game was frustrating at points, but I think it was in the good way that motivates you to overcome the challenge and (mostly) not the bad way. Awesome job. Fuck the farfalle starship swarms.
The only minor criticism I have is that your ability to handle the later levels seems to depend a lot on how quickly you're able to get the jump powerup. Considering how fundamental it is to the gameplay, I'd suggest making it available from the beginning but maybe putting it on a cooldown or giving it charges or something. That way I still have to be judicious with it, but I'm not totally fucked if the enemies swarm me before I have a chance to grab it (and sometimes the powerup comes in a lane that's already swarmed to hell, so there's little hope of getting it). I also wasn't sure which of the projectiles WAS the powerup at first, so it took some testing and dying before I realized it.
Really excellent entry. Nice work!
