The controls for the car aren't very smooth especially when the car goes backward sometimes the button isn't even registered and there is no proper player feedback when i collect/eat the burger was missing. For example, the easiest thing to do was to destroy the burger, but if you wanna make it a bit more juicier you should add particle effects and some sound effects. And the Retry button on the game over screen doesn't seem to be working.
Nice work on the 3d modelling though the burgers and cars look really cool. And most importantly congratulations on completing the project.
