Hi! The premise of the game seems interesting, even tough I personally think it doesn't have much to do with the theme of the gamejam... I can't really give an opinion on the gameplay because I got stuck at the second puzzle, it does not seem possible to me to connect only 3 machines considering some pipes can't be rotated, but maybe I'm missing something here...
Anyway I noticed the background ambient sound doesn't loop, so after a while the sound will stop.
