This game is HARD as it is BEAUTIFUL. I loved the pixel art and the music in the background was awesome too (if not for that I may not continue to push it until the end!).
The things that I annoyed me during my gamepaly were:
1) the ground was sliperry (often leading the character to a dead fall)
2) when the rope touch the a ledge - and the character is beneath it, they often became unable to climb the hope.
3) when the rope is near a ledge the character often let it go as it was on safe ground - and it wan not!
