Honestly, I think there's a real mistake in the balance regarding these two characters. The Monkey wins in any case if it's still alive and has gotten rid of the Kraken.
And the Kraken doesn't win against anyone at all, and if the Monkey is still alive, it's even worse. In short, the Kraken was in a very unequal situation.
It could have easily won
There are 2 key moments here: the Monkey revealing itself in the second night and a slight reveal before the Mafia in the daytime game.
The failure to kill due to the block in the 4th night, where instead of a comfortable ratio of 2-2-1-1, a losing ratio of 3-2-1-1 resulted.
