While players are doing their best to eradicate every last invader on the screen, they will at least be treated to some psychedelic backgrounds that rapidly change as game progresses. Should players access bonus rounds, the background will change to black with blue linings, while in ‘Fever Time,’ the backgrounds will have a purple hue to accompany the proceedings.

The sounds the supplement the game mostly come from the resulting effects of aliens dying from your ship’s laser, which have musical overtones in a sense that will remind most players of Rez, an underappreciated game from Sega that appeared on the Dreamcast and Playstation 2. The music has a bit of a techno flavor to it and is accompanied by a female voice that announces the title of the game, the stage that you are currently on, and whether you have gone into ‘fever time.’
