Heya! Unfortunately we decided to take the demo down, since in many ways it didn't represent very well the full version we were working on. Honestly I can't even remember all the changes we've made, but there were quite a lot of polishing done.
We just posted some new screenshots here :)
After the demo we actually moved back working on our main title, Tales of Esferia: Araxis and it's currently available on Steam.
If you want, I can throw you a free code for it via email, if it would somewhat scratch the itch of playing Archipelago :)
Lately we've been super busy with our day jobs and barely had much time to work on Archipelago, but we really want to get it done, but it will most likely take a little while. The goal is to release it on Steam (and most likely on here too) as a free game when we get it done.
