Калинка-малинка! A funny font made from Tetris blocks, and you even hinted at the origins of this game in R. The story of the game is really interesting. Maybe you should add some blocks at 8 and 3?

Oh, not Kalinka, I had to say Korobeiniki - this song was the soundtrack for the game. In childhood memories everything was confused and I was mistaken)

I seen the Tetris arcade machine in Crazy Quarters Arcade in the downtown Bay City area, and the R is backwards there. I'm not sure if they still have it or not cause I don't really go out as much for the time being cause pandemic

Could I also ask you not to rush so much with the Cyrillic alphabet? I don't really like those Д Ж Й, can you see how I made them in LCD family?
