I could play the game on steam? Just playing it today
You can, for now: Steam doesn't have a clear policy on what they do with the games they ban. Some customers reported they couldn't access their game anymore, while others can. I'm giving itchio keys to all the people who bought the game on Steam and ask for them, just in case.
But the game's page doesn't exist anymore, so you can't buy it on Steam and I can't access my developer's page (so of course updating the content is impossible). I think you can still buy unclaimed Steam keys, but since it seems the access to playing AHitD can be revoked any time, I wouldn't suggest to pay for that.
