Fun little game, but too easy, especially in unlimited mode. It really needs to get progressively harder when you're in an unlimited play situation. After I beat the final boss 4 times I just killed myself because I was bored.
One minor suggestion, show, for example, "Wave 13/15." Near the end of the later levels I keep thinking to myself "is it almost over?" but I don't remember how many waves there were supposed to be.
Awesome game, but the over-use of particle effects from the shooter traps made it run real slow on my older computer when there were a ton of those traps. I got killed by "lag" more than once.
The Merfolk Revolutionary, sometimes when he switches sides, he covers up one of my guys. Didn't know if that was intentional, but it seems like it shouldn't be.
Getting the same "This Version of the Game Can Only Be Played on Kongregate" error. I'm ON Kongregate!
You should test more before you release version updates
