I think the room for improvement is much smaller when it's content aimed at toddlers. I don't find it improbable that we've already reached the "peak".
I'm new to HN, but can see that the thread is no longer active (as in I can't reply). There was lots of great (and entertaining) feedback on the thread (especially about the terrible font). I would love to reply to those who fed back on the game and the page, now that I have ironed out some bugs with the game, and importantly changed the font to something that is much more readable (and with much better CSS). I've also released a mobile-friendly version of the game. Do you know of any way I can engage with those that commented?
Again, thanks for your interest and the two days of excitement I had looking at those analytics.
That's funny. I checked out your Twitter after the submission started trending on HN and saw that you posted the traffic stats. I actually wondered whether you would figure out where it was coming from, so I'm glad you eventually did!
Regarding your question I don't think there's any good way to engage with people after the thread has been "archived", especially since there are no DMs on HN.
Glad I could contribute to some excitement nonetheless. I posted it because I thought it was a cool and novel approach to a classic problem. I also really liked the article (and your homepage/games in general). Keep up the good work!
BTW - There's a mobile version of the game too now https://nonzerosum.games/tetrings_mobile.html
It was really cool seeing all those comments about the terrible font, and the game of course.
