It's still being worked on! :)
That being said, I am still looking for funding to scale development back up to a proper team, so right now development is quite slow and sporadic. Most of my time at the moment is spend on unrelated contract work since I do need to also make a living, but I'm continuing to do some work on Core Decay in my free time at the moment.
I am still hoping that I will find a way to scale development up, or at least be able to go back to work full-time myself on the game, and that remains the long-term plan! Right now things are a bit slower but I continue to look for opportunities to move forward :)
