These assets are made to be used.
"Asset flip" is low effort games that often have 0 original assets, that more often than not are also pirated, and are often made to just profit from the cards they get on Steam and the few sakes they will get before being removed from stores.
I would not call this a asset flip at all they just use a premade, probably to save time and money on making a original map
That is why i specified that the map is one. And if people want to use assets like map packs thats ok but they just took the demo scene and didnt put ayny work into the map... And as a solo developer this pisses me off because i love this game he needs to change the map though
