If anyone likes challenging dungeon crawlers I highly recommend keeping your eyes on this title by Bare Mettle Entertainment.
The combat takes a while to get used to and the game is very unforgiving but it has a certain charm that I don't think I have ever experienced in a PC game until now.
Exanima is currently in early access on steam for $15USD and is a prelude to the upcoming Sui Generis. It's a single player dungeon crawler set 20 years before the events of Sui Generis which will be an open world exploration RPG.
When you are given the option of holding a flaming torch or protecting your left side with a shield while you stumble around in the dark, or you might forgo both the torch and the protection and take your chances with the biggest weapon you can get your hands on.
