I respect intellectual property and am fully committed to resolving the issues! * Undertale By Toby Fox * Created By System, ZeroXilo, Crosu, Ptfk * Android Port By Ilka * Released By KYwoo The Story: Coming from a half-made universe, the Sans from this forgotten AU destroyed his own soul in order to escape. After falling through the multiverse, he arrived in a new, blank void. Now having no soul, he could no longer feel emotions. From this new void however, he discovered color, and each color granted him another emotion. The color didn't last forever though, so he bottled up every color he could, so that he could feel emotions whenever he wanted to. With the new AUs! Keep in mind that the game is at beta.

Installs
How many people have installed this game, as the storefront reports it. This number is worldwide — unlike the price, the same package answers with the same install count in every market we asked — so it carries no country. Each source below is a different kind of number and they are never drawn on one axis.

Google Play shows “50,000+” on the store page.
Play publishes a precise install counter alongside the rounded step users see on the store page. This is that counter, worldwide, as it stood each day we asked.
Of the eight storefronts we track, only Google Play publishes an install count we can read. Where a store publishes nothing of the kind, this panel shows nothing rather than a zero.
