Good game! The grapple mechanic is smooth, and the graphics and sound mesh well to create a chill atmosphere. The animations are smooth and fine-tuned to the tiniest detail, to the dust in the jump to the death transitions. I can tell you planned every part of this!
I also like the overworld! It feels like a level in itself, and it adds layers to the game. I actually had to put some thought before I could even go to a level!
Great game overall!
