I only played this in training mode. I think the concept looks fun. 1vs1 car battle with weapons. I wish we could see more in front of the car. I had a tendency to move the mouse pointer up, trying to “move the camera”. I didn’t try mobile controls, but it looks like the layout can work well. It was enjoyable to drive around the training map.
For a 2 week game jam, it can be difficult to include both 1vs1 against real players. Even more so to add an AI to compete against. I think I’d focus on the player VS AI first, as there aren’t many people who will play 1vs1 in a game jam. It’s still a great chance to test the concept, so do what works best for you.
