This game is absolutely EXPLODING with content without having any grinding and has tones of replay value on top of that. Each campaign (there's 4) is excellent with each knight having their own distinct gameplay style and (with the exception of 1) all having completely unique level layouts. While it seems that Specter Knight is the obvious fanfavorite out of these (and I'm inclined to agree) ALL OF THEM are top quality and worth your while. On top of that there's the added little mini challenges and a whole ass platform fighter in here as well (though it is a bit simplistic). Aesthetically wonderful too, this pixel style really appeals to me and it's complimented by a great soundtrack. Play this game.
