Not at this stage, Sileo is intended to be a free release so everything does release here on Itch free of charge, we just roll out new content one update ahead on Patreon to help cover development expenses and such. We are intending to make a release on Steam at some stage and we're toying with the idea of making the Patreon content available there for a one time purchase, but it's hard to say when that'll be - we're already juggling 8 different build releases with each update and that's already something of a headache
