See I considered that (and maybe I'll implement it in a 'bugged' gamemode at some point) but I kinda wanted the bug in this game to feel like an actual bug. So like, something stupid that the dev could've actually let slip through. And if it were a real bug, a cap on your bullets would never have been an issue :p
If it helps though, I did massive reduce the increase in bullets you get. Currently your #bullets is 10 -3*health, it used to be something along the lines of e^(-health). Which would've had you at firing more bullets than there are particles in the universe.
Making them into an arc at some point would probably be a good shout ;D
Thanks so much for the feedback though!
