Void Flux

Rad! You made it, and just in the nick of time. There’s, like, bright stuff everywhere. The Void has been disturbed, flux loops have appeared all around, and the dark matter is being drowned. I’ve trapped the charges you need in our remaining dark crystals; use them to cancel these fluxes. It’s up to you to bring back the Void! VoidFlux is an electrostatics puzzle dressed up as a neon crystal toy from the 80s. Loops of light strung across a crystal hexagon of dark matter, each carrying a number, its flux, that the dark matter needs gone, and charged crystal gems below: teal for positive, pink for negative, one burning core per quantum of charge. Use each crystal, bring each loop to zero flux, and bring back the Void. Between rounds there is Wittgenstein’s Tractatus retold in 80s arcade slang, shipping in nine languages, English, Polish, Spanish, French, Portuguese, German, Italian, Danish, and Latin, because an 80s Tractatus without a Latin edition would be rude. Three color-blind-friendly palettes. Game Center keeps a leaderboard and 25 achievements with their own neon artwork, and progress follows you between iPhone and iPad over iCloud. No ads. No in-app purchases. Just You, the Void, and a radical synthwave soundtrack.

Verdict
The clearest difference is price: RoBuster at Free against Void Flux's $1.99. RoBuster also leads on update cadence (daily vs every 5 days). Void Flux's advantage is ads (none vs shown) and chart position (#101 vs unranked). On in-app purchases and iOS requirement there is nothing between them.
