It looks great. Some parts break the game, for example, the weight-lever, if you get only 1 player on the other side the chain isn't long enough to go to press the button, and there's no way to get back on it. The level you created is enormous for a jam game, I would've remained a bit lower on the size and higher on the polish. Besides some minor issues, it really looks closer to an indie game demo than a 48 hours prototype. Really good job.
P.S we also created a prison escape themed game, if you wanna check it out :))
