Kore has been very active behind the scene. Development is happening it's just not public yet. Watch them over the next few weeks and I think they will surprise you with what they have in store. Check out the discord channel and bitcointalk thread

I have. It's a pump n dump.
They've done this before.

And that's where I got the inactive github link from. If they're really doing development why would they be promoting the link to a dead github?
Because they're not doing development and think no one will check the activity on the github. The github has 6 posts ever, activity over 5 days in the beginning of May 2015. This was never a legitimate project.
