Great
That was fun, I'm very impressed by the characters and villains- very very well made. Much better than most games I've seen on the internet. The difficulty levels are on the spot, easy is challenging, but most people will probably get through it on their first try, normal and hard requires more strategy, and though I haven't played the Epic difficulty I guess the player will need a thorough walkthrough or something, which is just how a very hard/epic/impossible setting should be.
My only problem with personally it is that it's pretty slow, and with the continuous stream of enemies, the gameplay becomes repetitive and boring after a while.
anyway cool
