I have been working on and off on turning my award-winning AKJ 2 entry, Misty Isles, into a full-fledged mobile release. The idea is to make it about the journey of Odysseus, following the story of the Odyssey but making the characters a bit more colourful.
It still needs a fair amount of work: more levels, character art, dialogue, sound, music, and some more mechanics to keep it interesting. But it should all be doable in a month if I put my mind to it, and approach it game jam style: "don't think, just do it".
Oh, if anyone has a good idea for a title ("Misty Isles" is a bit boring), please let me know!
