Batman Cup - Motorcycle Racing Game
Quite nice little flash game about Batman taking part in a race competition. The goal is to get to the checkpoint before timeout and to finish 4 laps per track. Tracks are quite similar through.
Batman Cup is a spin-off of the previous BNA game called Batman Road 2. The graphics is very similar, the Batman is driving identical motorbike, but the gameplay is somewhat different. Instead of shifting lanes and dogging obstacles, in this instance you compete against other bikers.
Ok, now let's put the pedal to the metal, the Batman style.
There are 4 different racing tracks you get to choose at startup and they all look quite similar. Basically you compete against 6 other motorbike drivers on a highway road near Gotham City. At some point you will be driving through the city tunnels and sometimes quite near the city buildings. Any type of contact with other drivers or with the objects on the track, will cause a rapid decrease in speed of your motorbike, so make sure you get into curves carefully. Up arrow key is used for keeping the gas pedal pressed and the bike quite easily accelerates to its maximum speed of about 170-180 mph. It's recommended to release the pedal for a second when you go around corners or lean to the left or right in curves.

Mitigating circumstance is that you don't need to worry about bike stability or traction, as the game take care of that for you, meaning that you can't actually fall off the bike or something. The most important thing, as said earlier, is to avoid contact as much as possible and to drive at maximum speed.
The track has so called checkpoints, which you must reach before the timer ticks 0. You have 30 seconds to reach checkpoint, and if you fail to do so in the first lap, you loose. It is not necessary to get to the checkpoint on time on higher laps, but you won't get any bonus points in that case.
Let me show you in video how I did in this game and that was only my second attempt. The video is right down below, hit play and see how it went for me.
