Pretty cool. Fun gameplay and art to match. Good job!

So the point was not to kill the agents? I loled :D
The game is a little bit unbalanced, after I read the description I won by simply clicking two times "bring it on".
Nice graphics though. And buttons could use the pointer:hand css markup :P

I didn't feel like a had a lot of control over what was happening, but I laughed every time I sent a new hero in, at both the hero names and the different rooms. Every evil villain should have an entire room dedicated to a Crotch Laser

Easy once you figure it out, but the potential for a very fun game is easy to see.
