SS is as simple as guiding an arrow that moves fast and try to make it reach its destination without crashing into anything. Very straightforward right? Just 2 buttons (hold the button to move vertically, and release it to slide horizontally), 3 game modes & 42 levels (the demo includes 21).
Then… you have the colored lines that change the travel direction, the slowdown option and many obstacles that will appear throughout the game. A great piece of arcade that you may try (or buy) this way.
