I think you might be suffering from success with your puzzles here - they're probably some of the best in the game jam, but it seems they may be difficult for people to wrap their heads around (especially if they're trying to look at a lot of games)
People that they do click with will love this though, great game
I've seen a few games in the jam with a similar idea, but I think the puzzles in yours are the best thought out of the lot. Your movement/platforming also feels comfortable and a bit more lenient to give focus to the puzzles.
One thing I noticed I experienced if you're planning on working on this more - in the third level, depending on where you're standing when the stairs spawn the player can get stuck. This happened to me and I had to restart the level.
Otherwise very cool, especially given the time frame!
Love the aesthetic, and you clearly hit the theme!
It took me a second to understand how the "trust" mechanic works (didn't know I had to pull one character with the other), but I think it's very interesting.
