You should look into their first abandoned game...Malice and the Machine, you can find it here on F95. Showed promise too way back when, now it'll never get finished.
As for the $20k a month, sounds like they lost some money moving from Patreon to SubStar...and the only reason we finally got the Charger animation was to drum up some more interest and get folks to sign up with SubStar.
Yeah, many have (and I have in the past) pointed out how Eromancer will do the bare minimum required to keep this cash cow farting dollars for him...sad really, if he put for the effort and tried to complete his game. Well, he'd probably have a 5-star game that he could sell on Steam and it might even surpass Karryn's Prison. But nope...so here we are.
Ah well, see ya in a few more pages probably.
