is there something i am missing or is this just maxed out in 7 rounds... over 1k bullets, max firespeed and over 250 damage.. all u do is kill the zombies that spawn? any win condition or is all the fun in the game lost after u hit the base the 2nd time... and what is the point of damage going above 5? if u want this to be a game not just a drool/clickfest... i dont know just scrap it imo. oh and cash per is broken beyond reason. it needs to scale up more than just adding 5 to the previous cost.
Good ideas :)
