It's more of an engine, than a game.

And with that if you put this into a full course game, like other people are saying, obstacles, different tracks, etc, then it would be a good game.

this game could be better.

what to add to it first:
obstacles to avoid. (you would also get health with this)
the ability to fall of the track and not just slow down when you get to close.
and a time limit this would give turbo a purpose.
and when you turn up the ramp make the screen go with it at all times don't just look at the side of the car that makes blind spots.
more then 1 lvl. and maybe a slightly bigger track.

later after that is all complete and you have enough memory space to add more.
have at least 3 action sound tracks to listen too.
customizable vehicles where you unlock the parts as you pass lvls.
a save feature to save your file onto the game...

Could have been better

It was pretty fun after you realizied what the controls were, but there was nothing to indicate what they were in-game. The sound could also have been a little better, a soundtrack of only 5 seconds set on repeat gets very annoying.
And why did the vehichle go to 3 miles an hour once you hit the finish line? What if I wanted to race the track again? Maybe it would have been better to have it go to a different menu that asks if you wanted to race again once you completed the track?
I did like the graphics, though, and I liked the feel of it a lot. Just... needs some improving.

?

It kind of sucked. I mean, were the controls really only the arrow keys? Was there more to the game control wise? And why did the car thing suddenly slow down to 3mph at the finish line? This could be much better. You could add more cars/racers, turbo boosts, numerous race tracks, weapons, a girl or robot with the checkered flag at the beginning, or maybe landscapes and backgrounds. It could have been good, but it wasn't.

It's ok

It's not the best game I ever played but it's good enough to pass judgement for me everything in the game was average.
