SERIOUSLY!

If you have these nearby generating coins at 31 delay which you don't have to do anything to get and I disapprove of....

Blaster: 50
Bouncy: 25
Ice: 15
Seekers: 50
RF: 40
Toaster: 40
TNT: 15
Pepper: 15
Electro Blaster: 15
is one possible set. Take note I never have tried to make a powerup system, as it makes it too easy to get weapons, so this is probably inaccurate.

You might want to raise or lower things depending on how the level is built, especially for bouncy.
