First official game jam I took part in with my housemate; Mini Jam #89: Pumpkin. We had 72 hours to create a game and the limitation was that we had to base our game off of a myth or legend, so we decided to do the headless horseman. I primarily did the programming, with some 3D modelling where needed.
Most models seen in the game were from third-party assets, as we wanted to focus on giving us enough time to execute the idea and get used to the time pressure rather than creating everything from scratch. Future game jams will be from scratch to further develop skills.
