wow, wow and at last wow. I'm a sucker for pixel art so you already won me at the start and music also enhances the atmosphere. The take on the game jam theme is also very creative! The only thing to improve is the camera that sometimes stays after the character and it's kind of hard to say what lies ahead.
As I said you won me with the pixel art and backrooms, the mechanics are not lacking IMO so I can't resist giving 5 in all categories, fantastic job!
