FireKart is really impressive for a first game! I had dabbled in making little games, and then my first game jam was the previous one, Mini Jam 189: Cooking. That's awesome that you're making games and taking part in game jams!
If you're at all interested, this is my submission in collaboration with Tazamo who kindly did all the awesome music! https://inferno1600.itch.io/pick-pocket
