This is so good! Such an innovative mechanic! This could totally be a full game!
I did experience a game breaking bug though. When I re-joined and accidentally collided into a moving platform, the game froze.
I really hope you continue working on this game after the jam!
Edit 1: I restarted the game, and this time I fell into the third gap here and never respawned lol. I'm gonna restart it a 2nd time. I really want to complete this game lol.
