Use the [up] and [down] arrow keys to change speed; press [left] and [right] to navigate. Press [space] to jump. To quit a game in progress and return to the road select menu at any time, press [esc].
You must stay on the road and make it to the end of each one to advance automatically to the next, though you may play any road you wish. While driving you will notice that some colored terrain have special properties, such as changing your speed or destroying you if landed upon. Also, the gravitational force changes between roads and so will the tactic required to make it safely to the end.
You are given unlimited lives, and there is no score tallied and no levels to unlock. This is pure arcade goodness without all the overhead. You will notice, however, that a brute force method will not get you very far; you will need to plan your moves and your speed wisely for each road. Great arcade fun in a fantastic Flash implementation.
The game was coded by Zooli and is actually a remake of SkyRoads, a now classic game released by Bluemoon Interactive back in 1993 as shareware for the PC (DOS). SwfRoads looks and plays a lot similar, though it does not include the oxygen and fuel gauges, nor the time limits that SkyRoads has. Bluemoon has since made the demo and full versions of SkyRoads freely available as downloads from their site.
