great game I got far enough here is my playthrough https://youtu.be/Gw2oePomhQM
Haha, just watched the videos, very funny!
You got about half way, there is a gate below the first building you come to where you use the key and carry on. I think I'll make a small change to make the gate more obvious as appears to be too hidden :) The game is finished, but not too big as just made during the Jam.
finished it great work, shit myself plenty getting surprised https://youtu.be/dmQSzbz7S6c
