Interesting concept and atmosphere. At first the mouse movement with the torch felt pointless but then the bats made it feel very important :P The angle of the camera makes depth perception a bit of a challenge, I was frequently misinterpreting where platforms were. Nice pixel art as well. I found it pretty challenging and couldn't get too far, a checkpoint system would be welcome. There seemed to be a lil physics bug occasionally as soon as the water touched you and you jumped where you could jump like 10x lol (maybe that's a feature?) Overall, great work!
