Fusion

Abstract game with single player, two-player and four-player keyboard layout. Maintain the spheres on-screen using primarily the firing key. Use the specified key to play based on number of players. It's recommended to use your thumb for the firing key. More players makes the game easier.

(use the secondary ability to start the game)

Ludonarrative (spoiler):

At 150 million C° inside an artificial environment of a fusion reactor, 26,000 times hotter than the surface of the sun and 10 times hotter than its core, two nuclei inside the reactor filled with plasma clouds fuse into one, releasing nuclear binding energy in the process. 

Electromagnetic field generators operated by supercomputers, making constant adjustments and calculation at microseconds to keep the plasma cloud from touching the reactor wall, producing energy without destroying the reactor.

As plasma clouds collide, the temperature increases, and clouds move even faster. The more collisions, hotter the temperature, faster the cloud moves, and energy generation increases. With peak fusion efficiency at 150 million C°, releasing energy equivalent to the Hiroshima nuclear bomb every 2 minutes.

Humanity has yet to master fusion technology due to the difficulty in containing the plasma cloud. When the EM field generator fails to contain the plasma cloud, the number of particles inside the reactor drops. Lesser the plasma cloud, lesser the collision, slower the remaining cloud moves, then even lesser collision, and the reaction soon cascades to a halt.

The game meant to simulate this process and make player understand exactly how and why fusion power is so difficult to control via the gameplay.

Fun fact, the SPARC (US) and HH170 (China) are the 2 most advanced fusion reactors in the world,  are projected to master such technology and become commercial-grade by 2027. 

HH170 is funded by Mihoyo using revenue earned from Genshin Impact.
