@thedarkne if u can't defeat the boss press tab and click back to menu then select a lvl which boss u can defeat, once u upgrade enough u can try to fite that boss again :P
i wish there was a beastiery and oso u shud not call it a sniper gun.. cuz sniper is alrdy a gun so rename it to sniper or if u want u can name it something specific ( dragunov, awp etc.)
how about a cheese multipliyer like if u win 3 rounds in a row ur mutlipliyer goes to 3, meaning that round u get 3 cheese but if u die ur multipliyer goes back to 1 :D
