I don't really know what to make of it, to be honest.
I love the way the game -feels-. Despite being graphically minimalist, it still has a looming darkness to it. Somehow fairly spooky!
The control system was interesting. Definitely takes some getting used to, but I don't think its bad. I think a beginner "tutorial" dungeon with some real threats would probably help me warm up to the engine more.
I really love how mindfucky the game can be, with your surroundings changing constantly.
I want to see more of this. Mainly, I want to know what kind of gameplay/combat there will be, and how the control system works with it.
The only bug I encountered was, while the "voice" was telling me stuff, if I used IJKL to inspect something, the text would overlap and be hard to read. I'm sure you've heard this already, but thought I'd share.
Overall, the art works, the audio definitely works. Keep it up.
