Congrats on your first 3D game!
I let a lot of pizzas go cold and I didn't expect to be immediately thrown into delivery, but I had a good little time with this game.
The driving felt surprisingly nice, and I think I've tried using the same building asset pack in a game project once but I thought the environment looked decent. Though I did reach a hard lock at one point and had to quit because a delviery square spawned on an empty void that I couldn't reach.
Also if I had to make a recommendation beyond plugging the level holes, and the delivery location logic, but having the triangle be an arrow pointing TOWARDS the destination would be a solid quality of life improvement!
Also I think even just a simple bike sound loop, a delivery sound effect, and a kevin macleod music track looping in the background would add a lot to the game. As it is now it feels kinda eerie in a way just silently moving around the nighttime streets.
I don't know that the game really feels so bad it's good, just more kinda felt like a first attempt at a 3D game. Which maybe could be SBIG by some definitions?
In any case good work on your first 3D game and second jam!
