On a mac, the scroll ball stick causes you to scroll down, even when in the flash game. thats why you have to play in a new window if you are using a mac.
i hate how it deselects the tower when you accidentally click on a creep. then i have to go back and click on it again, which make blocking creeps during waves very hard sometimes. aside from that great game 3/5
If you are gonna give this game a bad score because you cant control blockhead, think to yourself: Did I bother to read the INSTRUCTIONS? Do I have a slow COMPUTER? Do I hate it because I SUCK AT IT? Try to think these things over before rating it a bad score, because this is actually an amazing game. I give it a 5/5.
