Same here -- although I have a feeling it'll be more fair than Ms. Splosion Man or Super Meat Boy. One of the comments I saw from the Giant Bomb QL called it a "2D Dark Souls," which may not be entirely accurate.
I have only broke 3 controllers in the 20+ years i have been gaming and Dark souls was one of those (broke 2 on it, not because of difficulty but because of really stupid fucking mistakes on my part) and one on SMB. Again like DS it wasn't out of difficulty it was out of a careless mistake and arrogance that killed me and rage just completely engulfed me.
Oddly enough i never get super pissed over difficulty, i just get REALLY angry when i do something stupid out of carelessness or arrogance and it happens more often then not, i get too cocky :-/
I'm actually finding it funny rather than annoying, some of the deaths are so stupid, and they're always your own fault
I imagine it's going to lead to an awesome Rage Quit though.
That's what scares me, i get pissed over stupid mistakes that shouldn't of happened in the first place but did because like i said above, i got careless, arrogance blah blah.
I actually didn't even find Demon's/Dark Souls to be THAT difficult, i just made a lot of stupid and careless mistakes which got me killed A LOT and i got really mad over it.
