Yes, my idea was you can play the game normal but if you want to be stronger you have to by upgrades but less upgrades mean more points for killing. If you kill a zombie with no upgrades you get 100 points if you have 1 speed upgrade for example you get 95 points each kill.
Yes i did but there is a bug with the damage upgrade you can only update it when you have exactly 5 coins if you have 6 it wont work. And every Upgrade costs 5 Coins but the laser costs 50 Coins.
