I like the atmosphere at the beginning! I think maybe you should have kept the tone more serious. I think you undercut your own atmosphere when you add in jokes and references to other games. Which is a shame because the atmosphere is the best thing your game does. I would definitely avoid using other games copyrighted material like key art. A game like the stanley parable can get away with a minecraft reference because its a heavily self referential game and its of superb quality. Jam games do not benefit from making references to real products since the comparison is almost never favorable. But well done on the atmosphere, I think if you had made a more serious horror game you might have had a great one!
