Demon dome is exclusively a side project for when they need a break from PoP, it's not a new main game to split focus on, and i haven't noticed any slowing my self with their release rate?
Yup, this is one of their side projects, the main project is Portals of Phereon, arguably one of the best adult games of all time.
Demon Dome has less content/rules, but it is more content dense and focused, fun game
