People are still playing Slendytubbies 3 multiplayer

[FanofSTSince2012]

I swear, I have the BT Games Android port of slendytubbies 3 and went to multiplayer, I saw people in each server, but the port uses a older version of slendytubbies 3, so what are the other people doing online on this website? Why aren't people using LumaUtils to play multiplayer?
