SkyRoads is one of the game I kept playing together with my friends when I was studying in secondary school. It is a very addictive game that can train our reflex. The 256-color VGA graphics and soundtrack is good enough to keep us playing.
There are may levels in SkyRoads. Of course, the difficulty is increasing in higher level, and really need a lot of training to get pass all of them.
In SkyRoads, we control a simple space ship, and use left, right and space bar to jump form a platform to another platform.
Failing to do so, the ship will explode and we have to try again.
