My hesitation to repost them again was about that. The assets themselves are done from the ground up, but there are elements that take such a heavy inspiration (things like tostarena buildings, or the dragon head in ruined kingdom), but then there's things that are more ambiguous (most nature tiles and some new donk city buildings, for example)
That's why I started developing the MyPixelWorld project on the side, to make similar biomes to those devolped here but making them commercially viable. On October I'll post the first MyPixelWorld assets, they will be done in a similar vibe, but you will be able to use those commercially.
