Speedtouch is a lightweight entertainment game that tests your reaction speed.
On the game screen, colored spheres will turn yellow in random intervals. You have to hit them with the finger or the stylus as fast as possible. If you're too slow or don't hit the spheres with the required accuracy, the game is over. Try to survive as long as possible to reach a new highscore. To help you, special blue spheres slow down the frequency of new targets.
The game principle is simple to understand, you might know the idea from whac-a-mole type games. Nevertheless, or maybe even because of this, the game is addictive and you'll want to beat your previous highscores.
