Wow what a creepy intro. Honestly from the cover image and when I first started playing I didn't expect it to be as creepy. Very cool concept. The combat feels a little floaty, but otherwise works well. I had a bug where I couldn't interact with the potion on the first floor and the difficulty is fairly high, so I died pretty quick. Second playthrough I got a little further, but still very hard especially the ranged enemies.
Great job overall, no real complaints except the difficult could be tuned down.
