Rockman no Constancy is a hard romhack of Mega Man 2/Rockman 2. So of course, there is a hard mode rom that is even harder.
The differences between the hard mode and normal are:
-Enemies take more hits to kill
-You take more damage
-Stun invincibility is greatly reduced, meaning you can't "tank" your way through any of the game.
In these videos, I will save state between levels, but each video is a single take. Of course, there are dozens of failure videos I won't upload, because this game's too hard for me to do in one shot.
Heat Man's level is probably the easiest. The birds are a major annoyance, and the disappearing block section can be really tricky too. The boss battle is relatively simple, but takes forever and is easy to lose concentration on.
