This is a well-made Bitsy game about a creepy hotel.
Bitsy is a minimalist text and pixel art animation game engine. Here, the author has modelled a hotel with quite a number of items scattered around, and multiple rooms.
The ambient messages you find around are effectively chilling. At one point, I was checking something out the second time and the game changed drastically. I made a choice, and got a very interesting ending.
I don't know if there are multiple endings. If the one I found is the only one, that's neat; if not, I appreciate the branching. Overall, a very strong bitsy game.
