Hi tankbuster! I watched this game on the live stream, and thought it was a must-try. I think that it was spectacular that you managed to do this in the 3 days.
The cinematic intro was amazing, and the voice acting was great. I think the game could be polished, so the car doesn't crash as much into random ice. Saying that, it's a jam game so it doesn't matter too much. I think that adding mouse controls for the camera would also improve the user experience.
Overall, you did a great job, and I look forward to whatever you do next!
