If you like the idea of a puzzle-type game with rpg elements (different classes/skill perks, level-ups and upgrades to gear, etc) that's easy to pick up and play for while, you absolutely must purchase this game. It's awesome for getting that rpg fix from time to time while having the "let's try to beat my old high score" kind of feel as well. There are 4 difficulty settings, I've only played on normal (the 2nd easiest) so far, but I definitely feel like it's a game that I could get countless hours of enjoyment from.
Check it out, bros.
