@Austin Thanks so much!
This is a great point and something we went back and forth about a lot. I am going to post in more places today and hopefully we'll see a bit more traffic. If we are seeing consistently high traffic in those windows we will extend the times where it's playable.
But because you need other people to be online while it's being played, and currently we're not seeing very high traffic even in those periods, then hopefully this format at least maximises the chance that people can play every day.
I like the idea of adding a share button to the homepage. There is currently one after you complete a game, but it could be good to incentivise people to share so that they can play straight away.
On the point of playing vs a friend, this might undermine the Turing test to some extent. I think if you know that the other person is your friend you have a lot of insider knowledge that would allow you to beat even a very good LLM agent (or another human)!
Thanks very much for your support and these suggestions!
