There are no obvious bugs or glitches and while the textures aren't great, they're not terrible either. Unfortunately the game just isn't any fun. There's virtually no challenge to speak of. You can hold the accelerator down the entire time--brakes are completely unnecessary. The courses are very wide and turns are very forgiving, and you'll generally have the lead by the middle of the first lap--and usually hold it until the end. The game needs to be more difficult. Tighter turns. Narrower tracks. Make the nitro a riskier proposition instead of "use it all the time and you win".
a game should not open a new browser window within the game. I literally just searched "hot dog" in the google search bar above the game and went to a different page in the game window.
