RIGHT?! Roads/rivers is hard. My biggest concern was it would be a pain in the butt to try and find the right road to connect the right way out of...what 50 odd pieces? ^^;; But everyone who's doing procedural map stuff probably wouldn't have cared once they set it up to just work, so I'm glad you added to the set! The stuff you're doing is looking awesome! Thanks for sharing it ^^
Yeah, you'll probably notice those extra roads are yours with extra paths added in using the same palette. I am... not an artist. I was going to do the others, but after roads I was mentally done lol.
But for the gen the rivers and stuff are fine as 4-directional. I just needed 6-way roads as the player would be placing them and they'd probably find it odd to not be able to go up and down. Without your originals I definitely wouldn't have been able to add in the extras :P
