2 issues and a bug.

[ghost]

I got a seed that gave me a very small jump(due to strong gravity), and I couldn't make a jump toward the end of the introductory stage. I even tried clinging to the edge and jumping across from there, but that didn't work either. As a result, I couldn't beat the introductory stage. It might be a good idea to let people escape the introductory stage just in case this happens, but it would still be a problem for climbing up the fortress in Sigma stage 1.

The next problem occurs if you get a boss room with a platform jutting out from the middle of the ground. If you beat the boss while standing to the left or right of it, Mega Man can't get to the center of the room. He'll run against the center piece endlessly, causing a soft lock. Perhaps you can make it so that Mega Man clips through it? It would look goofy, but it would solve the problem without you having to do away with that room type.

There are rare occasions where at some point, when a boss is about dead, the game will bug out making both Mega Man and the boss invincible. This happened to me while fighting the robot guarding the capsule in Sting Chameleon's stage, and I've seen a YouTube video where it happened to a guy while fighting Sigma's first form(AKA Jedi Sigma).
