In this small arcade game, the player controls two catchers simultaneously—one on the right and one on the left. In the game, particles always move toward each other, and they must be caught at the point of collision using either the right or left catcher. If an annihilation is missed and it explodes, the player will lose one heart. Losing three hearts results in a game over.

A successful catch grants energy, which accumulates in the drone at the top of the screen. The drone consumes energy while operating. The player can choose a target for the drone: it can either convert energy into victory points or spend it on upgrades. The number of points determines the maximum upgrade level.

There are four types of upgrades:

Multiplier — increases the number of points the drone can extract from a single unit of energy.
Capacity — increases the maximum amount of energy the drone can store, as excess energy is always lost.
Energy — boosts the amount of energy gained from catching a single annihilation.
Work Speed — increases the amount of energy the drone can allocate to point generation or upgrades per second.
The goal of the game is to score as many points as possible.
