Hello, this is my first post on this forum.
I've been playing Kirby recently, and I got an idea while playing that game: the Vacuum Gun! It allows you to suck up damaged enemies(or jellies), then spit them out at other enemies. This will do damage to what ever you shot out and the enemy you hit (the damage would very, depending upon enemy you shot out).
It could also vacuum up items, fixing this problem: http://forums.spiralknights.com/node/232
