Poorly balanced, ammo system makes no sense, and the most expensive weapon in the game (chainsaw) is worse than the 2nd most expensive weapon in every way. Lots of video lag too
Upgrades on Support towers doesn't appear to work properly, I had on range towers upgraded to the 400 dollar upgrade, and while its range showed a 2nd tower being under it's influence entirely, that tower didn't get the range enhancement while another tower (adjacent to the support) did
Bad collision detection, inability to turn off all sound (the dog still barks even when you press the sound button), and no obvious way to tell what dogs you can eat.
