The Crystal Catacombs: the dully named but ever-shifting prison where Vasil Ravencraft will most probably spend the rest of his life possibly admiring the wondrous (and exquisitely pixelated) sights. Unless, that is, you decide to enter his shoes and have said misguided, treasure-obsessed adventurer fight and platform his way through the treacherous, shifting dungeons of a truly great Metroidvania/rogue-like hybrid.

Crystal Catacombs is available for Windows, Mac and Linux for $10 and you can always try its demo before buying.
