Build a versus mode against a past game

[timotheeg]

• Use a 2 player layout and save it as a single player layout
• Current players is displayed on player 1
• Load a past game as player 2 and start replay is at speed 1 when game for player 1 starts
• Stop replay on game end so player can compare his run versus the "opponents"
• Somehow advertise "famous" games to play against (e.g. Jounce 1.6M, Eric's 6.4M, Yobi's 777k PB 😜)

Do POC with CTWC23 layouts, or perhaps with a layout which shows the running tetris rate, so one can compare the TRT pace after death.
