the issue is that you've developed the preconception that the dev is lazy after narrowing on a couple screenshots that showcase a total of 4 assets that he made himself from previous games, these 4 assets being character sprites for characters from another game who, in all likelihood, aren't going to be anything greater than easter eggs for the player to come across. All the while, you have ignored the other screenshots that showcase fresh assets he has created, such as player character sprites + various outfits, CGs, and UI. There's more effort on display here than non-effort. So yes, me saying he's not being lazy is an assumption, but there's more backing my assumption, especially since nebel geisterjager exists and that game shows that the dev is capable of producing high-effort and is likely to continue doing so, than your assumption that he's lazy after focusing in on a couple screenshots and ignoring past productions.
i understand the bar is low for h-games, RPGM ones especially, and i am pretty cynical about devs for these kinds of games myself, but i feel like your claim is incredibly nitpicky and baseless
