Interesting concept and a really nice narrative! I like the sense of vertigo it gives you and how it makes you question about why the character is climbing and why are people just watching xD.
If you want to improve, the movement is a bit clumsy and sometimes the camera penetrates the building and since there are no cues on the controls I didn't know if I was moving the right way xD. But if you simply map them in the itch page it will be enough :)
You deserve praise for making such a nice game by yourself, a bit of music to set the tone and some more polish on the movement and you have a terrific gem in hands.
Congrats and nice job!
