While I do understand the seperate features of steam being exclusive, as someone who bought the game already I'm not interested in buying the game again.
I do understand its not as simple as "Flip the switch and give everyone Steam keys" since I know Steam takes a cut. But as someone who bought the game on itch, specifically because the cut they give to developers is significantly higher, I'm not going to double dip in buying here.
Again, I get the reality of being a small dev and needing to get paid for your work and how the Steam version is expanded upon. But as a customer and a fan, I just can't justify double purchasing, when I bought a version that I didn't realize would be feature incomplete.
