(8-6-18) So yesterday, I was browsing the Google Play store, and I realized that "WorldCraft" and one of the three versions of PoC on Google Play known as "Survival Multiplayer" have been tooken down from the play store, in fact looking further into it, all games under the developer name "Solverlabs Limited", such as WoC, PoC, their bird game, their river game, their Monster Hunter game, and their Texas Poker Hold em' game, are removed from the play store.
However good news for us is, we have "WorldCraft"/WoC "WorldCraft 2"/WoC, "Planet of Cubes"/PoC, and "Planet Craft"/PoC on still the play store as those games technically aren't under the "Solverlabs Limited" name, but instead in developer names like "Plabs" and such, though I'm certain those are Solverlab's secondary developer names.
Basically WoC and PoC was taken out of the Google Play store, but kinda not as both games had three versions of them before one version of each was tooken down.
Edit (8-18-18): Another one of PoC's apps have been tooken off the Play Store, now Planet Craft is the last, and only app left on the store.
I wonder if Solverlabs know about them being tooken down?
Old Question before finding out that Google Play may be trying to get PoC off the Play Store.
