I've got some suggestions: 1. Make a level balance between teams.
2.You could add a vehichle at between levels 30 and 100 (mabye a motorbike)
3.It would be awesome if you could add in-game achievements rewarding with exp.
4.An idea is to increase the gravity when you reach a certain height so players won't just fly around when they jump off mountains.
Btw great game, i wish you a good luck!
Yeah, there's some good guys (and gals) that play CF !!
