Doing something in 3D is ambitious for a 48-hr game jam, so kudos for that right off the top! I feel like what you've created only very loosely fits the theme of the game jam, though. The monkey-head bauble could have used some snapping to the pedestals, and the player movement and jumping felt pretty awkward. I feel like it could also have used a pause/quit button option and an indication of the controls.
Congratulations on putting together such a big game in 48 hours! That's an incredible accomplishment, even if the game has some problems.
