A great entry point for anyone interested in the old-school style of first-person dungeon crawling RPGs in the veins of Wizardry and Might & Magic.

The mechanics are simple enough to allow you some depth in how you gear your characters without needing to spend hours spreadsheeting whom should wear what for efficiency.
The story and world lore are barely existing but they provide enough background without slowing down your dungeon-crawling.

My only criticisms of this game is that you can't alter your party composition mid-game and most item abilities are not really explained in-game.
