Pros:
- Well designed and detailed dilapidated, almost underwater city setting.
- Exploration is fun.
- Good character design.
- Subtle but emotional plot (much of which is told through the protagonists drawings, which is a nice touch).
- Character and boat control well enough.
- The art design is beautiful, and the lighting is stunning.
- Very easy to run.
- Photo mode.
- Great for achievement hunters.

Cons:
- Very short and repetitive gameplay loop.
- The majority of the gameplay consists of collectible gathering
- Very slow pace (though this may be a pro, if that's more what you're looking for).
- Movement can feel a bit janky, but it's not bad enough to be a deal breaker.

Overall an enjoyable and aesthetically beautiful game, however I'd be reluctant to pay full price for it.

Interesting story and game play.
