This is nicely made! I especially like the music and graphics of the game, it add so much charm. The mechanic is also quite innovative too, although a bit hard to play I still like it very much! There is this one bit or criticism where the ghost can go out of bound revealing all those parallax background, and it really breaks the immersion of the game. It should be simple fix though so it's not a big deal.
This is a very good entry and you should be proud of yourselves! Well done!
