Hello,
Thanks for this tutorial, it's really nice and does a great job of explaining the rules!
I do have a few pieces of feedback:
-As another comment pointed out, it's quite hard to read black text on a dark background. Maybe consider switching to white text if possible.
-The section explaining the clock's rules at the beginning of the tutorial is quite clear, but I would emphasize that each of the game's 40 clocks is different, and that the rule you're explaining (the sum on each segment must be equal to or higher than the previous one) applies to all clocks in the game. I would also mention the infinity symbol in the center of the clock, which allows players to have a sum greater than 24 on any segment, whereas this isn't possible with many of the clocks in the game.
-When explaining the discussion phase, I would also emphasize that players are encouraged to discuss and establish a strategy or shared conventions together.
For the rest, I think it explains the game really well!
