Well, to quote Joe Strout: "Soda is a side project; it hasn't had a "champion" to push it forward in quite a while, and I've been busy with Mini Micro and related things. I would love to see someone breathe life into it, though!"
I believe its API is supposed to resemble Mini Micro in many ways, so I wonder how difficult it would be to move a game made in one to the other, that is, once it's more complete 😁
