You're asking a lot for a 3 hour development =P
But you're totally right.
I never played megaman all that much, and my homie who did the art/music chose the concept. Movement acceleration is easy to do... But again, time haha.
I would have loved to have a scenario that taught the player the environment/enemies, but this was a lot to implement. Had to scrap the planned enemy mechanics and do what was simple.
There's no health bar, so everything is 1-hit-kill by design. The checkpoints somewhat make up for it, but I could have added more.
Thanks for playing and I appreciate the feedback!
