This is your second game?!?
Excellent old school graphics, lots of different weapons (which many will recognise!), a smooth yet definitely hard to master control, great music and sound quality, humorous, challenging... we have a winner here.
What's lacking? Not much despite maybe MORE characters... but most of all, a single-player story mode would be SWEET!
All in all, this is the level of the "Megaman VS" games ; read: if you're a self-respecting Newground user/visitor... then play this game!
All in all, can't wait for upcoming updates/new versions. You have a really good game idea here that was pulled off well! Personally, the Labyrinth Zone is my favorite map because of all the water and arena changes gimmicks that add to the chaos.
Well, that's all. Have a nice day and thank you for your time.
