Lv1. took the inspiration of particle collision, player able to drag the silent particle to hit the flying one and making a collision. Once a collision happens, the pattern appears. The pattern’s design referenced the image of particle collision on the LHC (Large Hadron Collider), and combined with the idea of supersymmetry. There are five compositions in total. If the player is able to create five collisions before the timer goes off, they will win the “dark matter”.
