I liked the atmosphere, and visuals. The lack is sound kinda makes it scarier in some points. The idea of peeling the walls to find secret sigils is very interesting, but I'm unable to tell which is good and which is bad, there should be some sort of sign. For some reason my mouse pointer wouldn't disappear like in other games where you look around with the mouse like Minecraft or Content Warning.
Overall, great work! I'll play this game more later and will see if there's anything interesting else!
