Hey! I'm here
Look, I don't know very well how to make custom GFX, I don't know if it's posible to have a 2x2 pencil in Paint.net for make the sprites...
But I know how to recolor, and I recolored a old tileset from Castlevania for my project Attack of the Darkness, for a level based in Forest of Doom from Castlevania Portrait of Ruin
I decided to recolor the original sprites for make them look like the Forest of Doom tileset from Castlevania PoR
and here it is!
