Pretty good Megaman fan game, and its difficulty is really accurate to the original games' difficulty. Pick easy mode, even a baby can win this game. Pick normal mode, you've just entered hell.
The one flaw I can find with this game is that Tank Man doesn't have a bulge and you can't perform those sprite oddities found in the original games. Overall, 10/10, it's definitely one of your best works along with Koopa's Revenge 2.
