Not a fan of the use of a LOT of copyright material, with that said. I was having fun with the number game. Would be nice if the number was randomly generated, and maybe make a sub game happen during the guessing (IDK click a blue dot, that pops up on the screen before it disappears), and if you fail you loose an attempt. As for the hidden items that was very weak. If you at least wanted to make it a little more challenging black the screen, and have the cursor look like a flashlight. Heck you could even add a few jump scares, and a timer to intensify the mood.
Best of luck with the next game.
