Remix the project & add a sprite of your character panicking, then dying once the blocks hit the top of the screen! For help with timing, use the "DIE!!" broadcast message. The "2" broadcast message is for events that take place once the "GAME OVER" sign appears. Add as many characters as you want, just don't go overboard with adding 20 or more characters at a time.
If that stack of blocks reaches the top of the screen, it's over for us all! Of course, that's exactly what happens since the player didn't bother to move the thin grey block out of the way... This remix adds Paul & a "GAME OVER" sign. Credit to all, especially @TehRises for starting this remix chain and Nintendo & Alexey Pajitnov for being the original creators of Tetris!
