WallRunners for Mac

From Cinnamon Computer Products, Cinnamon GameSoft Division:

WallRunners, which in its primitive days was known as SuperBike, is a very simple, yet extremely addictive shareware game for Mac OS. The two-player mode is an absolute blast! In the not-so-distant future, cybersports, played across the Internet, are the primary source of entertainment and competition. The most popular of these network sports is WallRunners, where two players go head-to-head piloting special bikes which leave a wall wherever they go. The object is to entrap your opponent before she traps you. To keep things interesting, each player has one missile that can be used any time during a game, which blows through any nearby walls, possibly giving them an extra chance to win. WallRunners v2.0 has been completely rewritten from the original SuperBike "hack." The same tried-and-true gameplay design has been retained perfectly, but the entire program is greatly improved in every aspect. The play control is now flawless. Keys are perfectly responsive, and do not repeat, preventing accidental suicide like would happen before. Also, every key on the keyboard (except Caps Lock, for obvious reasons) is a possible control key. Yes, you can now choose your own keys. A Strict Play option disables the missiles if you so choose. And perhaps the biggest improvement: the new computer player AI is quite a bit smarter and actually pretty hard to beat. It has no strategy, but is nearly flawless in its gameplay.
