After the last games were all guessed early, these ones seem to be a bit more difficult. More hints:
#31: Transferring the soul of an animal into a child born without one will not end well. Anyone surprised? Killing a god may the cause of it all. You are the Watcher.
#30: A-Plus, Akebi, Ramen, S-Chan and just Frank. Deliver the cleaned laundry. Actually you forget to deliver it.
#29: The rooster of war! The tree of love! This colorful open world game let you interact with some gods.
#28: Climbing, swimming, running, flying, digging... and freezing. Luckily there are hot springs, which will warm you up. Guessed by Darashiva.
