Thanks for playing the game. You got that spot on, I set the Freeze Z value for my player character, but forgot to do so with the enemies and the bullets.
I would have added the sounds if I had few more hours, I actually missed the deadline by 5 seconds, literally the questionaire caused me to do that, and then I had to email Mark for the extended grace period.
Also, the enemies were supposed to shoot as well, and hitting a planet was supposed to drain health, but couldn't happen.
Well, it was a good jam. Thanks.
