Pros:
- naval battles where we control ship are really interesting

Cons:
- naval minigame - not only it's super slow without ability to turn on auto-combat, it's also not possible to auto repair all your ships. It took me once 25 min to lower danger level on all trade routes from red to green...
- capitalization of words in subtitles in the middle of sentence.. why?
- literally no other content in game than main quests, rest is just copy-pasted filler activity
- upgrading ship is really grindy, as you can't buy iron and wood. But you can sell them for profit... so you have economy where people can sell certain goods, but not buy them. Yay?
- inability to buy more than one hunting good at a time, so it requires a lot of clicking. Funny enough you can buy a lot of ammunition at time. But not hunting goods. You can't also craft few darts at a time
- sorting menu system that cycle between available / acquired / not owned. But when you use available to buy filter, items you already have (or can't afford) are still visible... again why? It makes whole filtering system utterly pointless when you still need to browse through things you already have (or can't afford)
- game is without closure, I literally thought I go to start another quest, not see to credits
- underwater sequences, where sharks patrol area, waiting to kill you.. seriously? I know they had to make underwater a bit dangerous, but repeating this stupid superstition that sharks just swim around, waiting for people to kill them??
- main character is not likable. Well he's not unlikable either. He's so... empty and shallow
- there is only one good sword / pistol set you can get quite early in the game. Rest is visibly inferior, so it's pointless to waste cash to buy it. So you're stuck with yellow menu highlight, indicating there is something to buy. As items don't get de-highlighted when you hover over them. Like they should
- neither Uplay nor game save playing time. I'd say something like that is basic functionality in XXI century

Conclusion:

It's fine Ubisoft game, with exactly the same gameplay like in all other Ubisoft games (only non-standard thing is nicely made sea combat). I run around, unlock towers to uncover map (and shitload of pointless collectibles), and sometimes find my way to main story quest. Story is average "pirate wants to become the best pirate", and shallow like a puddle. I wanted to play in Watch Dogs, as it was also free on Uplay. But as I see that AC:1, AC:4, Far Cry 3, FC: Blood Dragon are carbon copy of each other with different guns - I will pass. And most probably won't play in another "main series" Ubisoft game ever. Because games like Child of Light or Valiant Hearts are way better than them.

If you like Ubisoft games - you will like this one as well, as it's more... of the same. If you already played in few Ubisoft games and have enough - don't look here. Naval combat may be nice, but it's not enough to turn this game into something more than.. "generic Ubisoft game".

Pros:
- interesting and easy puzzles
- some characters speak with rhymes - can be counted as cons for some people
- graphic style is light and pleasant
- light and not complicated humor

Cons:
- lack of map
- already acquired collectibles are not marked
- bug which made it impossible to get all achievements, due to faulty camera work - after transition from previous level camera is locked at the end
of next level. So it's not possible to move around, as we in fact move character that is not visible - so don't see where are walls, paths and so like
- forced returns to hub area after beating the boss
- combat controls can be wonky, and fights are more annoying than interesting

Conclusion:

Some ugly creature steals our ice, and we can't have drink without ice! So we go on adventure to get our ice back. It'd be start of the game summary. Turns out we're inside someone's head, and need to fight their fears in order to bring back normality (and ice). Best thing is that main character doesn't do it because of some higher goal or need to bring order. He does it because it's annoying to leave things as they are. As normally he'd gladly lay down and do nothing.

We solve simple puzzles to progress. For example - there are clouds of poisonous gas, and we need to start fans up to blow them away. It requires starting them in certain order, re-purposing batteries to turn off fans we don't need, and power up platform or other fan we need. So it's nothing demanding, but made well enough to keep me entertained. There are also time-based sequences, but thankfully they are rare.

There is hub area, and 3 routes branching from it, with boss at the end. They must be completed in certain order, as later levels are unlocked when we beat previous boss. And here comes my main problem with this game - after beating boss I'd want to go back to hub area on my own, and collect items I missed along the way. But it's not possible, game automatically kicks us to hub area. And to collect missed things, I'd need to again go all the way to the boss, and then all the way back. As you don't get "magically" teleported to hub area 2nd time. Game should ask if you want to go back to hub area, or stay on level with the boss.

Overall it's fine game, but nothing extraordinary. It does feel like nice game for kids, as puzzles aren't really complicated. But timed sequences or wonky combat in narrow areas could be frustrating for them.
