Thank you for keeping sfx a little lower than the music. It bothers me a lot when I adjust volume for music only to have a blaring sfx. I liked the concept but I had trouble understanding how each character worked before I read the description page. Even after I did I still couldn't pick up boxes with the strong guy using shift. Also when I tried to throw the other characters he only threw them left for some reason? The music was chill but maybe too chill for your challenge level? I did have to get used to "jumping" with a fan and using spacebar to swap characters but I did enjoy the experience. I would recommend moving them a little faster though :)

Really interesting concept. I'm sorry you guys had trouble on the build you got uploaded. The puzzles seem really cool from the level I played. I did have a few bugs like the tinker building the box immediately instead of waiting for me to place it, unless that was intended. Also my players got stuck on the fans in the lower level. 

Overall pretty good use of the theme and interesting game.
