1.Vizuals: When I saw your videos on Discord I wanted to play this imediate! Now I played it and want to tell you that the Car and the Character are both wonderfully made. On the other hand, if you do not have enough time, consider using assets. You do not need to use the asset strore or package manager for that. Unity uses so called FBX data for Models and most of the Free and purchaseable 3D models are FBX ready. You just need to drag and drop them into the project folder in unity and they get initialised (include the texture file :D ) You can see clearly on your game that the Time for Modelling stuff was not enough, but you made a very cozy looking game with funny shaped trees :D
The Signs would have neded a backside on some of them to read them from both sides.
2. Audio: I hat a very unpleasent ticc on the motor sound which made the game unplayable for me with sound because it sounded like someone scratched my inner ear. it is like wrrrrrrrr ITCH wrrrrrrrrrr ITCH ...... and so on. Everything else was very well done and fitting!
3. Mechaniks: The core Gameloop is working perfekt! you made the pickup, the drop in the car works, it shows where to go, you can enter the car and exit it, very very nice! I just had issues with the camera, most of the time when I was walking and not driving. but thats a issue you can fix easy with more time I guess. Overall very well done!
Summerized: You made a very cute and nice Game that is playable and fun. Some more flashy FX or more flashed out worled with people other cars and cities would make this game into a nice little Steamrelease ^^
Good Job and Happy new Year!
