According to the devlog on the game page itself, this game was not built during the jam.

Hi, first of all this is the changelog in scratch (because the game is made in scratch), the game has been updated other times before releasing on itch.io for new feature and mostly for optimizations due to change of platform. Then, to be sure, I checked another time in the GameOff Jam page, and there aren't indications about projects published for the jam as un update of an existing project. Let me know. Sorry for the problem
