You have created something really interesting here! I played a couple times with some friends watching and kept finding new things. Personally I got pretty scared a couple of times, and rightfully so! The way you programed the game making it tame for an hour or two and then something freaky happens is gold!
I'm really glad to have played your game and I would be willing to pay for the finished product! I'd also recommend putting the game on Steam to draw more deserved attention, even if this game is heavily inspired by other properties, you still used them to great effect!
I can't wait to see what else you add to this game!
