Thanks for putting together a Halloween game! Some thoughts I had that might improve the experience:

• It's possible to go through many of the walls. Players might think this is unfair
• It might be more engaging if the character rolled or had some movement animation.
• The character is a bit hard to control; increasing the turning and movement speed/acceleration could help
• I saw some images from Banjo Kazooie in the game... you might want to replace those with something that doesn't have a copyright

Happy Halloween!
