This is a simple game that launches quickly, plays quickly, and ends quickly if you’re not very good. You play as the red particle, and try to avoid blue particles. The controls are straightforward: move your thumb to where you want your character to go. It is suggested that you keep your thumb on the screen versus tapping, as the former is easier.

Changes:

Added Highscores, made the game run smoother, and a few other small improvements
