Love, love, LOVE the demo!
The characters were engaging, and the art was gorgeous! The characters' proportions are often off in VNs, but in Saleana the proportions were perfect (did I mention that the characters were mesmerising?). Aside from the occasional grammar mistake and some word choices that seem out of context, the story (at least so far) seems promising.
Great work! Can't wait for the full game!
P.S. I'm using a mac, and while I couldn't open the file manually, I could open it through the itch.io app. Just thought that this bit of info might help!
