I can't believe that people are asking this because it's so simple. I will list the steps chronologically:
1. First you make the little yellow man go all the way down to the bottom left corner.
2. Then you click your quality to medium "M"
3. Then you click your quality to low "L"
And magically the door appears!
Interesting that the Quality controls have three options which decrease lower, and lower...
you must click high quality medium quality then low quality then the door appears
All you have to do is beat it then u could pass
453 is the answer
sorry, no idea
sorry, no idea
Press shift five times rapidly.
count the numbers up to 453
kill the other car
count the numbers up to 453
go to youtube and type in walk through level 13 or what ever level you need
you got to be lvl 12 or 13 or 14 or 15 i was lvl 15 when i beat him
