Short, but sweet! It's a great idea and I like that there weren't any frills. It was very straightforward. The game was a bit dark in some areas and while I didn't mind holding to interact, I do wish I was able to move faster. The space was small enough that speed wasn't a deal breaker though.
I would suggest that any scary moments, you program it so the character is looking at it. I missed a few things because I was looking somewhere else. You did a great job overall, especially with having multiple endings even though I only recorded one, you executed the idea well and made great use of the space, the game looked great, and I definitely think it's worth continuing to tell the story using the same mechanics and style. Good job and good luck!
