You can't use it in 2.8 because it requires the Blender game engine. It is meant for gaming. If Blender decides to bring back the Blender game engine this will be updated to that new version of the Blender game engine. So you are still stuck on blender 2.79 but look on the bright side. The blender game engine is still new on the 2.79 so that's all what is new right now. Whenever the new one comes out then it will be the old. So you're going to still need a second blender launcher to 2.79 if you want to use that so you are still stuck on two of them. If you know what I mean with two software.
