Pretty intriguing so far! I like the atmosphere and the art.
Unfortunately, the "restart" and "checkpoints" options don't work for me. The game also crashed after one of my choices right after the red light. (not sure if it's the choice itself or a coincidence, but just in case i went "you feel... confused" > "but you don't want to feel like this" and that's when it broke)
There was also a slight error in my third playthrough, where I went to find the sledgehammer but didn't pick it up. I went back to the door and after i stopped kicking it, i got the normal follow-up to that and then i got the follow-up text where it was as if i'd used the sledgehammer.
Looking forward to the development on this, though!
