And then to add to my other comment.... you REALLY need to add an exit button or something because i clicked to join a round, then realized i forgot to apply something. Now every time i join the round i have the arrangement screen covering everything.
A few things i think should be added, first hotkeys for the spells, and second a way to exit the menu of playing a level once you click on it... Other than that so far great game :D
This game could really use some work... nice graphics but the upgrades dont do anything. By level 10, with the 10% damage boost, you should have a 50% damage upgrade. Shooting a zombie 5 times at the start, and 5 times after your doing 50% more damage just shouldnt happen...
Finally beat this thing on epic... (yes it is possible to beat). Little tip for epic mode... KEEP THE GUY WITH AUTO-LIFE ON HIM! (and sometimes even the girl.)
