Fun start. Good foundation, but could definitely do with some guidance/tutorial and things to let the player know what's going on. I love the visuals and audio you've got going on, can make for a spooky game for sure. One thing I might suggest is either zooming out the perspective a bit or making jumping less extreme. It's a bit jarring to jump and have the screen scrambling a bit to keep up.
But like I said, definitely a good start to a game here. Seems like there's lots of underlying systems that don't really get to shine and I feel like with some polish this could be a cool game for sure.
