This game is an excellent example of the richness of the rogue-like genre. An FPS rogue-like is hard to find, much less one that is done this well. Even though the graphics are blocky and pixelated (an aesthetic that most seem to love). I still found myself scared silly. That's because there is no telling what is around the next corner.
Nothing is sacred, nothing is safe, which is exactly what makes for a good rogue-like. I love the environments, the variety of enemies, the random potion effects, the quick interface, and the difficulty curve with each deeper level that you venture into.
If you're into rogue-likes, then you owe it to yourself to check this one out, even though it is still in Early Access, I cannot wait to find out what else the devs will be adding to this title.
