That's something I can definitely look towards in the future, as I consider the first pack the prototype to garner interest and feedback to build a much larger library out of it!
Hi! So, for the most part, they are different areas. But if organized in the same tile index, grassland and snow can definitely match as seasons. Desert is a different story as it has a fairly different cliff texture, meant for more variety rather than matchmaking.
But now that you mention, you just gave me an idea for a future patch of sorts =)
