What an absolute treasure! Highly enjoyable way to play one of the hardest games of my childhood. Everything is a lot smoother and forgiving compared to the original. I also loved the little backstory, not sure if it's canon.
Just one thing: I played as Megaman against Elecman, and managed to kill him after I was dead (returning Cutman boomerang). I respawned as Elecman at the beginning of the stage.
