At default settings, I run out of ammo on the 1st enemy, and it never recharges.
At cycles = 60000, I might be able to take out a few enemies, but ammo regeneration is still incredibly slow. A few levels in, I'm supposed to protect a ship, but I'm so ammo constrained that it seems impossible.

The framerate is also incredibly low.

Another issue:
If I turn on unlimited ammo, it doesn't seem to let me progress to the next mission, even after successfully completing it?
