Very enjoyable and relaxing :)
It was pretty easy to understand after a little bit of trial and error. I like how the game doesn't really punish you for playing "badly". You can just increase your success with strategic play, but there's no real failure state. That's pretty fun and keeps the game relaxing and low stakes. The strategic decision-making was also fun, especially with the introduction of Big Fish.
I got to the open ocean and kept wanting to play!
