Yeah, I agree, Mega Man Unlimited takes things too far with the tedious death traps. Not only that, many of the regular enemies and dangers just do too much damage; and the enemies are awkward/too gimmicky in how you attack them. It's almost like MegaPhilX played Mega Man 9 and decided "How can I top that brutality?". Then he saw Mega Man 9's Superhero mode and decided "How can I top that brutality?" Then Mega Man 10 came out and he decided - well, you get the picture. It seems like he has a notion that everyone loved Mega Man 9 due to its ball-breaking challenge, so his game would be loved for being even more challenging.
Well, it's not an AWFUL game either. It has some great ideas (and terrible ones, however) and, stuff. And it's nowhere near as bad as Mega Man Project Zero in terms of mercilessness.
Or how about that piece of crap Mega Man Paradise.
