I've actually been considering doing KTLA in full as its own game; when I passed it along I thought all it really needed was art, sound and decent level design. Though I will feel a little sad that I can't use purab's character design for the MC, I might try to ape it through my attempts at sprite art, and I might replace my medieval dungeon/torches idea with stars on a starscape. That or work with purab to finish the thing with his own art ideas... but probably not cuz I don't think itch has a messaging system.
But for the rest, somebody actually posted a follow-up Jam for this where you take games that didn't make it to the end and finish them up: https://itch.io/jam/games-we-passed-jam
