Boy I could not figure out the climb and jump mechanic but this had a real cool escape room vibe to it! I would love to see this taken further, reminds me a bit of Blue Prince.

I did play Blue Prince some time ago so there was definitely some inspiration there. I don't really know what you mean by climb and jump, but I guess it's about Mizikori Peak game. If you hold space when shooting your grappling hook it will make you jump after reaching the wall, later you unlock another ability where you need to hold space in the air to glide, hopefully that helps in some way.
