O mg, thank you so, so much for this wonderful message!! I am beyond happy to know you’re enjoying the story! You’ve chosen a good RO, indeed. Leire/Luca’s dynamic is one of my favourites and I can’t wait to show more of them in Act 2, and especially in Act 3, hehe :D.
To answer your question, for now I’m thinking on just using this page, since once you pay (or donate, actually) the amount that’s asked, you’ll have access to download the game in any format and it will be linked to your account. So, for example, you play on PC but for some reason you want to change to mobile for another route. Here, you wouldn’t need to pay for the game again, and I think that’s a pretty good advantage. But in the future? Yes, of course I’d love to release it on Steam and Play Store and Apple Store! These last two I’m not worried about because I have seen that the Monaca platform works pretty well to convert Twine games into mobile apps (and it's something I'll have to do anyway to release it here), but Steam seems a bit more complicated. I don’t know if Monaca would work to convert a HTML file into something that Steam would allow to be released on their platform, and if not, I don’t know of any other tool.
TL;DR, this game will be available for purchase here on itch.io. Maybe on Steam, Apple Store, and Play Store in the future, but it’s not my priority for now unless I discover a tool to make it work on Steam.
Thank you once again for the comment! I hope you have a fantastic day :D
