Lovely game, and good use from procedural generation didn't feel like I ran into the same level. I like the upgraded system and how you contained all the game mechanics within the actually game level. The monochrome pallete also make key things like health and enemies stand out so much more. Looks really good.
One note is that it would be nice to have one jump when you're grappling, it'd make it more fluid when scaling platforms or trying to land on another.
