Bud like I said in my reply, I've seen the screenshots. DigiBang wasn't the first to use these assets and he won't be the last and I don't agree that the morphs used on them look the same... I wouldn't be surprised though if that Dev was influenced by Digibang.To add what Nosferatu Suran said, if you look at this preview image it looks like very much to one of digibang female characters (don't remember her name), plus the icons, that are also very similar to this game.
Maybe he was already creating the other game, he got banned from patreon and was frustrated for the lack of support, so he killed two birds with one stone. Just my two cents.
Personally I don't think it would make sense for him to abandon the game as it stands with the amount he has already invested in it, I could believe that he might have put it on hold while he figures out his financial situation (like I also said).
