Best enjoyed fullscreen. Wasd keys (well, just WS) to go up and down. when the health button appears, click it to get full health. Avoid the rebel gems, collect the poofed gems and gem shards. Your aim to collect 1000000 of them :) or... just as many as possible. Press 'K' to skip the intro. WARNING: THIS IS NOT THE SAME PERIDOT AS IN THE SHOW! THIS IS SET DURING THE WAR!
Thanks to 78960_2 for the base cat flying game. I tried to change as much as possible to make it more original. Credit to Rebecca sugar and other steven universe peeps for characters, visuals and music.
