[scriptless]

There are 4096 usable tiles in the tileset. There are also, 4096 tiles in the level. Technically speaking couldnt each level use it's own tileset then? Allowing for an unlimited number of tiles (on an overworld or inside map even)..

I might also be mistaken but wasn't there a way in scripting to update only part of the tileset with overriding tiles? Sorry I can't remember but I thought I heard something about that half a decade ago.

1 Thing is for sure tho with tilesets. The ability to have tile layers OVER the player would be beyond amazing. But you would need transparency in the tileset's to do that perfectly.
