I'm doing well too, thanks!
Wesleyan Tetris is the worst version of Tetris I am aware of that is bad on purpose. It goes out of its way to pick disadvantageous pieces for you, makes up new pieces, occasionally gives you a piece different than the one the Next Piece box was showing, and insults how you play. It's an example your game should strive towards.
There's Hell Tetris, based off the xkcd strip and having a round floor. I would expect that you've heard of it. All the existing recreations I can find are in Flash, so that could be something to try recreating.
Then there's the launch version of Tetris Ultimate on PS4. That one... That one is not something you want to imitate.
I hope you enjoy these!
