A lot of the Mega Man romhacks (and MM9 and 10) that I've tried on the Everdrive really miss the mark in terms of design. I can rip through any of MM1-8 in no time, but much of the new stuff and hacks rely too much on blindsiding you, or swarming you with enemies, or poor enemy placement, or spikes everywhere. The original games were tough, but they're totally beatable and don't require much, if any trial and error. Just reaching the boss room shouldn't be a grueling task.
It makes me kind of nervous for MM11 when it comes out. I'm hoping the Inticreates people aren't the ones making it, because they don't really "get it" in my opinion.
