Cool story. The game is a ton of fun. One of my friends purchased a 4 pack and gifted a copy to me and 3 of us played it last night for close to 4 hours straight. We really liked it.
It is a unique game. Diablo/Torchlight type combat, but no loot, your character unlocks active and passive ablities you can choose to use, and there are 4 different classes you can switch between but you can only have 1 of a class playable at a time (2 people can't be the same class at the same time), it has a stacking mechanic where each time you attack a mob it gets these bars on top of it, the more bars it has the more damage it takes so concentrating on the same ones (at least for stronger ones) is worth the effort, and each level has puzzles, from either had to advance through the level to how to kill certain mobs and/or bosses. There is a lot of content in the game as well and it plays nicely. The voice acting is pretty decent and the writing at times was pretty funny as well. We all really enjoyed it and only stopped playing since it was 3am.
