A fairly simple game which reminds me an awful lot of the game Space Taxi. You're some prehistorical figure with some kind of helicopter-bike and you have to transport people to their destination platform. It may sound easy, it's not. Your wooden bike-chopper isn't that happy if you land too hard or if you crash into platforms, walls or birds.
The game isn't that fun until you find someone who is at least as bored as you are and plays along. The multiplayer function can make this game actually a rather fun game to play!
Ugh will never become one of my favourites, but it's good for a smile. I'm not recommending it, but if you feel you don't have anything better to do at all, try it!
