I love the simple but nicely done art. The mood is there. 
I would love a game like this with a player controller a bit more sharp. 
I feel half the time I fall was because of slippy pixel I don't know ahah.
Maybe you could also add an area at the start that makes you understand the core mechanic of the grab before going into the first pit ! Like small stairs, one first easy jump and all.

But love the mechanic of jump grabbing my way up. Very cool good job !

Cool idea! Kind of like a Getting Over It style game in a really clean 2D pixel art style which I love. I could definitely see this becoming a big game for streamers who love the punishing yet quirky gameplay. Not sure this is necessarily my kind of game, but I think you did a great job with the visuals and game design. I wasn't 100% sure of the connection to the theme, as it seemed like I could spam the rope infinitely, but it was a cool exploration of a really promising concept!

Love the graphics and the atmosphere! It might just be my skill issue, but I wasn't sure what I was supposed to do when I was on the first level, and wasn't sure how to advance :') Adding a guide would be nice!

Cool gameplay and graphics style. It’s that great combination of “infuriating” and “irresistible” :)

There seems to be some little glitches tho. A few times, I grappled onto thin air.

Made it to 23 m, then slipped and fell all the way back to 1. Yikes!

Nice theme interpretation, also like the artstyle! But sadly I am really bad at such games, so did not get pretty far .
