This was honestly a lot of fun. I originally was thinking I was just going to try it a couple of times and then write my review on it, but the next thing I noticed was that I was playing it over, and over, and over. Sadly, I could only get a highscore of 61, but I struggle when it comes to using the 'Q' and 'E' keys for quick decisions. However, with a little more fleshing out, this could easily turn into quite an addictive arcade game. It has an appropriate level of difficulty, and the challenge curve flows perfectly.
I did find one major bug in the game, though. If you place the barriers very quickly in the same spot over and over, the car starts to rotate at an extreme level. At first, this is good because it makes the car resist you and can keep you from spamming that move. However, if you do it just right for long enough, the car will rotate to a completely horizontal position and stop driving. At this point, the score just keeps adding up, but nothing happens and you can't get the car unstuck. My suggestion would be to add some code to check for angles and correct the car's position if it angles too far in one or more directions.
Overall, I really enjoyed playing this. It was short and sweet and definitely had that addictive flavor to it. Great job! You did really well on this. :)
