Sorry, your icon just caught my eye because it's the logo for the PHP package manager Composer. I know it fits your user name but I had to acknowledge it.
There are two games in development. The first, DRG survivor, is made by an entirely different team and is actually a proper spin-off.
Rogue Core however is made by the original team and originally started life as a DLC for DRG, but they quickly realized it wouldn't really work with the existing gameplay loop and decided to make it a standalone game instead as that would give them more freedom with it.
