It includes some bonus sprites and more color variations, but the core content is mostly the same. Generally for patrons who have kept up with the releases, you are right and it's not a necessary purchase. Thanks!

Yeah, there's something that I don't understand about currency conversion-- this one is set to require a pledge of $7 because it's intended for the $10-tier, so I hoped that would work to give some extra padding for other currencies. It's most likely that I messed something up :P I'll send you a download key to your patron account. Thanks!
