Hi PixelHole, we were thinking of an 1-bit aesthetic for our game in GMTK Game Jam, and we thought your free asset was the perfect starting point for us. As you realize, we have made changes to the tile set to suit our specific needs. However, we do acknowledge you as the main creator of this style (your name and itch.io link was mentioned in the readme file) and we will continue to give you credit upon launching our final game! As far as ideas go, I think that some more environment styles would be a really good addition (you have made the dungeon tile set, maybe add Forest, desert, cave ...etc). I am happy that you reached out and I hope we can stay in touch. It would be cool to get your feedback on the visuals of the game as we move forward with it.
