I joined GGJ this year too and made use of Spine! Due to stuff I had to do I could only participate for 14h instead of 48h but I managed to do the characters you can see below :> (octopuses, crabs and balloons)
The game is controlled by smashing your hand on a cereall box on top of which you placed your phone and is a local multiplayer. We also added keyboard controls for itch.io.
At first it had to be a VS battle where these 4 creatures were battling each other because it was everyone's birthday and each one's balloon was taking space from the others, then it became cooperative but we kept their sad faces because yes.
You can play the game directly in the browser here:itch.io
The game was made in Construct 2 so we had some problems with the Spine Runtime that did not support shear, paths, and other stuff, so we tried to go with what was possible and fast to do, and this came out!

I recently played a couple games by Double Fine Productions, if you can tell... :notme:
