Really simple and great game, with a nice atmosphere to go with it.
Really enjoyed the simple gameplay, it was also the perfect amount of stuff to do. Fits the theme well.
The movement felt a little weird, the jump was a little low, but also the fact that while jumping if you let go of the movement keys your character falls straight down felt a little jarring, a little momentum kept would help this.
Good stuff, a unique take on the theme!
