I mean "take over" isn't really in the cards. Just working towards the conclusion was... not that much fun for me, doing it full time? No fucking way. An artist I am not, that is way too stressful (I am not looking forward to more art for the conclusion). I am perfectly happy with adapting over creating, that was always the main focus of this project.
I do hope this version has helped push more subs to Ferdafs, although I can't imagine his 10 month absence helped maintain his subs.
As to "massively took over" I can't really speak to that either. I don't even know how many people play this version, let alone the unity version, as not all download sites display numbers, and both games end up being hosted by multiple other sites (f95zone being the only place I'm active with the game).
