I tripped over some LP youtube video of this game and in 15 seconds had to go buy it. LRG show sold out so I went the steam route.
This game takes the best of Castlevania 2 and Zelda 2 and leaves all the garbage.
Image how awesome Castlevania 2 would be with a mini map, quest log, and decent direction (clues, hints, dialogue that made sense). There was no way I would have beat Simon's Quest without Nintendo Power, solely because of the awful translation and worthless clues. Infernax fixed that. Infernax doesn't slow pitch the clues BUT they do make sense. Some you're bound to miss but when you figure it out (or google it), you're going to feel stupid.
I have yet to find anything I don't like about this game. Any castlevania 2 or zelda 2 fan will dig it. Any platformer fan that's good with gore will dig it. Metal fans will get a kick out of the achievements (so far everyone I've got has been a metal song).
It's great, check it out, you'll thank me.
