No, thank you!
Yes, I'm using an old save file.
Where will the game develop further? Will there be a pentomino mode? Maybe achievements, story mode, cascade mode, or something like Pokemon Tetris with collectible?
In my childhood, I had a so-called brick game, hardware implementation of Tetris. There, as you score points, fruits were shown on the right side of the screen. "Achievements" my youth.
