This was interesting. I really dig the narrow and elongated viewport married with the climbing mechanic. The jump took a bit of getting used but I ended up appreciating how it forced every jump to be entirely 'deliberate' if that makes sense? This was especially true during the "fog" portion.
My favorite part of the experience was the dynamic jump sounds, they seemed like pitch shifts throughout the duration of the jump... maybe something else too? The audio element tied everything up nicely.
I am still trying to ascribe some meaning to the ending :)
I enjoyed this little experience!
