That's funny you mentioned it feels like Megaman. It actually uses a movement scheme that is very different than Megaman (My game uses acceleration while Megaman is infinite acceleration. My game has variable acceleration in the air and drag values, etc) but when I was in tuning the movement I kept adjusting the values till they felt right and it ended up feeling just like Megaman... :/
I guess I just really like the Megaman control scheme :)
