Didn't got time to play & rate it during the voting period and I do apologize for that, but I really wanted to try it out so here I am. :-)
I do love tetris so I had to play it. And I loved it! Lots of clicks here and there, but that was okay to me. I didn't clearly understand first that I had to click that right button to set a block, but that's probably because my eyes were busy figuring out the best way to stack blocks on the other parts of the screen, haha.
Really cool, and good job! <3
