Hello ! Thank you for testing the game. Hopefully we'll get the sensitivity fixed in a post jam patch !
I assume you're missing the yellow console, you need to jump on that fallen pillar in the main room. Apparently this platform is not as obvious as I thought :)
We were also thinking that if you get stuck with the cable on your way back you could disconnect it at any moment and look for a way. But you're also right some later mechanics could have led to those situation too but we couldn't implement them .
