This reminds me of Worlds Hardest Game, but with a spooky atmosphere. I managed to get to the end, but it took a bit too long to get there. Some levels in the middle/beginning was too hard. But I feel proud to have completed it :D
The only big problem I think is the lack of originality. It wouldn't be a problem in an ordinary game jam, but sticking out is a big deal in this one.
Also, you can't walk diagonal downwards while using you pause ability. That is especially annoying in the level that MB got stuck in.
