Thank you for your feedback.
I agree that making your own assets uses up much valuable time in a jam, and if it were shorter I'd probably have gone with a box on cylinders, or got a car asset somewhere. But I also enjoy making my own assets, I feel it lets me express myself visually. And since there was enough time in the jam for it, I sacrificed some time to do that. The only bit that was really just indulging myself were the car doors. The game would be just as playable without it, but I really wanted to have the doors open ;)
Good idea about the signs hawing text on both sides, it would also mean I don't have to have a flag on them which way they are supposed to point :D
The trees, were a compromise. Unity's tree on terrain tool just doesn't work with ProBuilder meshes (I used that to model, was quicker than re-learning blender) and I just couldn't get it to work other than using geometry primitives, and I wanted cartoony trees, not the more realistic that you can build in unity.
The audio pops are annoying, yes, I couldn't find a way to fix this in the WebGL build, I had a note in the instructions saying "sorry about the sound just turn it off" but I seem to have deleted it when I was rewriting it.
I'm already working on fixing some things and improving others, the camera is also one of them. I tried a different configuration of cinemachine and it's much nicer now.
Thank you for your comments, I do hope to flesh it out into a more complete game.
