The overall look and feeling of the game is great. It's pretty brutal, but I assume that's intentional. I would've liked to explore more but was swarmed by enemies. Some feedback:

• The controls of the game were never clear. It took a few death until I even knew I could attack. I checked the game page, but never found a confirmation of what was bound to what. I picked a fire ring early on, but never figured out how to use it.
• It would've been nice if enemies were knocked back after being hit. Even if combat is meant to be hard, I found the combination of the confusing control scheme and lack of knockback to be more frustrating than fun.

That said, it looked like there were a lot of areas to explore. It would've been nice to have figured out what the fire ring did and if there were more hidden items that unlocked more features.
