What is an asset flip?
> An asset flip is a type of shovelware in which a video game developer legally purchases pre-made assets and uses them to create numerous permutations of generic games and sell them at low prices.
In this case, maybe not "numerous permutations", but throwing together the (presumably purchased) assets with the bare minimum components of a video game.
This game simply used a bunch of assets that were bought on the unreal asset store which is different and tbh completely fair especially with a small dev team.
