Your github repository goes way back before this jam started and I found no correlation between the theme and the game.
Game is something I enjoy but I reduced my scores because of the first line. I did not check the whole repository line by line so If I am wrong reply with proofs and I will give better scores.
Wow! I admire your vigilance.
We did some tests in the repo before the theme was announced to test the technology. These were cleaned up on 2-Nov after which the real work has begun. You can check here: https://github.com/olivergreening/gameoff-2023/commit/35aebd613ceeb2ae18043686cccf605a822be5e3
The correlation is that you press SPACE and the car scales up. Press SPACE again and it scales down. There really isn't anymore to it.
Thanks for playing!
Going small was easy enough to win the game and because I did not got stuck I actually never used that mechanic. To be fair if I could not progress some of the obstacles if I am not big would make the game more fun. I improved my ratings.
Edit: The game also don't go full screen but this could be some perfect pixel limitation.
