Game is good. Rewarding (i suppose, i am quite bad, but i did have fun with it). However in GOG's version there is a serious lack of online play capabilities which is not mentioned anywhere and is nearly hidden in game itself (i did have to look outside of game to find what was the problem). If someone likes crawlers or roguelikes with pixel/voxel graphics i would recommend it. With one caveat: Dont buy this on gog. It's a trap.
