Unicycle Delivery Service is some kind of Crazy Taxi clone. Make deliveries in a certain amount of time. Nice game but for my taste it is to much motion and rotation in the game. The best way to play would be on a revolving chair. Also the frame rate is sometimes not that high due to many high quality models in sight. You can try before you buy with the lite version of UDS.
