The concept is simple but so much fun. Currently hooked with this game and I can say that it is lots of fun run after run. I have been trying lots of rogue-lites lately and I have to admit that this game is underrated. The sequel has improved lots of aspects but this game did amazingly back as a standalone release back then. The style and the essence of the game itself is special. The strategic bit of the game is mostly focused on stats and how to balance this based on your armor and runes. Totally worth it since this game packs a huge game time and replayability value. Can get a bit repetitive after too many consecutive hours but after taking a break it's still fresh like with any game. Reccomended.
