Thanks guys! I'm glad you're enjoying them.
Tiny 16 won't be expanded on, sorry. It was an experiment in seeing how few tiles I could get away with and still be functional and I've accomplished that I think. The palette is the Dawnbringer 16 palette, and I think I used every color in the set. If not, Dawnbringer's stuff is easy to look up.
I've made a collection over at
OpenGameArt.org for tiles that should work well with my set with a bit of recoloring. I did fiddle around with expanding Tiny 16 for a while, but honestly it just isn't set up well for expansion. Too few colors, too simple in style.
I'm in the process of creating a new set that's similar enough that they could be used together, but this new one is more complex and made for taller characters (the size of 2k/3's sprites are perfect). It also uses Dawnbringer's 32 color palette and I'm trying to make the style work well with elements from both Vexed's POP series of tiles and Despain's Time Fantasy or Old School Modern sets if you're willing to do some recoloring and slight editing. It's an interesting balance, especially when I still want it to be my own style most of all. I have a ton of artwork done for it, but I don't know exactly when the first set will be coming out. It won't be free, and it will be multiple packs, so yeah, huge. Lately I've been focusing on just finishing the exterior stuff, and I think I'm close, but I've always been terrible at judging release dates.
