Developer here. The engine I used is Clickteam Fusion 2.5, which doesn't really require heavy coding so I just worked on the game for a week without using Github. I just realized today it's required so I just uploaded the MFA files onto this Github repository I just created which are the files Clickteam Fusion use for developers to edit their games. I hope that's enough. I really started working on this game last week and I'm happy to be a part of this event.
