Very nice little platformer with a very nice atmosphere. I love how you managed to create a pretty vivid world with such limited resources.
Making the game screen based was certainly an interesting decision and I’m not sure I love it, but it kinda works. As others have mentioned, a little more indication how strong your jump will be might be nice, but other than that, I got a pretty good hang of the controls pretty quickly.
All in all, one of my favourite entries so far. Nice job!
