So what needs to be done.
Well the only sound effects are at the start, so maybe there should be some optional background music (3 choices, and a mute button).
Also, there should be more levels of difficulty...
For example, that could be the easy level, but the harder levels can have potholes, mud, zoom pads, awkward twists and turns and other obstacles.
You could also show the results for all the laps, and give the player the options of how many laps they want.
The car should also be customisable. They can maybe choose the car colour, the size of the car, and maybe they can alter the specifications of the car (e.g. power, steering etc.).
There can also be a countdown race, where the player has to do so many laps of the track in a certain amount of time. If they do, they proceed into the next round.
And there's 2-player, and comp races, but it would be best if you made a different game for that.
The graphics are nice and clean though.
Thanks for reading and good luck.
