Hey! I'm an experienced tetris player. This is a funny game and you did a pretty good job! My only complaint is that you didn't implement any types of spins except tspin doubles. I suggest looking at the hard drop wiki for more on what I'm talking about! I tried doing j and l spins, t-spin triples, I-spins, z and s spins, all of which didn't work. SRS is a beast and I totally understand if you can't implement them for whatever reason.
It was a good game though, and I'd like to see more in the future!
