Apple has a policy of removing apps that haven't been updated in a few years, even if they still work fine. I don't have the resources to relearn deprecated build pipelines for Adobe AIR, so it's out of my hands.
After the death of Flash and then its similar removal from Google Play, this was the last place you could still play the game. After it gets taken down in February, it probably will never be widely available anywhere again.
It's not a perfect game, and quite different to what I would have made from the same idea today. But it was deeply influential to my path as a game developer - I don't think I could have got to where I am now without it.
Last year I tweeted some more about the game and its development history for its 10th anniversary: https://twitter.com/Draknek/status/1463235073029951493
