I been participating in the Global Game Jam for ten years, and of course I didn't missed the one this last weekend. My and my team made a small game of a farmer rabbit who has to make ends meet or the IRS will take it's farm. He has to harvest as many carrots as possible without over-exerting itself and suffering a herniated disc.
Also, we have the brilliant idea of using Godot, and engine that we have never even touched before, but it ended up being extremely friendly and we kinda fell in love with it. If you want to try it, it can be downloaded from the event page, though we didn't have enough time to implement several thins, like audio (no music or SFX I'm afraid), the art for the menu and a scoreboard.
