Maybe I missed something, but was there a way to lose? I got 8 levels and all upgrades never seeing any losing condition. I'd recommend having the items not overlap each other when spawning. Made it hard to see what was really there. Congrats on your submission.

Thanks for playing the game!
You've missed it, but to be fair I didn't get to implementing the level(s) the way I wanted. So the way to die is hitting the walls more than your health bar has bars left... That's why you can buy repairs, but it's so simple to just no hit the walls :D
The items spawning is just a time restiction thing, I new about it, but never got around to fixing it.
