I like this game, there are still a few tweaks and bugs to be worked out but it's fun. Also, this could just be me, but consistently the engineer AI becomes stuck in one of the medium levels at wave 17 from the west gate. Put DPS near your outer barricades to kill them.
I'd like to play more but it won't progress. I get more than the target damage and the stop button doesn't work. Only after 3 clicks does anything happen but that makes the round reset and score go to 0.
I like these kinds of games, and the puzzles are fun but the big red "WRONG" really doesn't reinforce gameplay, kind of makes me want to shut it off. 2/5 Nice try, but a trial and error game such as this with a big "You Suck" when you try, not so much fun.
