What a weird, cool game! I had a lot of fun with it, honestly! Really interesting interpretation of the theme.
I could easily see this being expanded, with more synergies between the cards and more cool stuff to do with the clock!
If you wanted it to fit the theme a bit more, you could have less slots in the clock and have the hand run multiple trips around each turn. Or maybe it could even continuously move, and it'd become a real-time strategy game!
