Would be a really cool game if not for the bugs I've found. Twice now the game has gotten to a point where there are no longer any enemies coming and yet the level keeps playing as if there are. With no way to cancel the level and go back to the menu(s) I have to refresh the entire page which then brings up that I've completed the right amount of levels and my upgrades say I've purchased them but they don't appear in the level. Also, all my weapon upgrades and mana/spell upgrades are missing in this case. If not for this substantial set of bugs this would be a pretty cool game!
