This game is awesome. It takes everything from Dave Gilberts other adventure game, including the stuff that is less awesome.
The puzzles this time are harder than the ones in the Blackwell games, but still not that hard. If I was a more seasoned adventure gamer, the score would definitely have been downgraded to four stars, but if you're a novice, the difficulty is perfect. An addition to the gameplay are the small minigames that are decently challenging and does add something to the game.
The story and characters are great and unpredictable. The story is good and avoids tropes and cliches. It's Dave Gilbert, that's all that really needs to be said. This guy is a genius. The voice acting is good, the narrator from Bastion is even in it. One thing that really saddened me was the lack of voice acting when you inspected things. While this could be understandable, since there are four characters, I really hope that they use voice acting for this in future games. It was jarring.
The graphics are not the game's strongpoint but it does the job. The artstyle however is good. The graphics don't really matter anyway. They're nice to look at, that's all that matters.
In Wadjet Eye's previous games, length, or shortness rather, has been a problem. While this game isn't that long, it's still longer than their previous games. I think this might be the softspot.
In conclusion, this game is fantastic, and I seriously hope that we'll get a new Blackwell game soon, and that it has learned the lessons of this game, being longer than the previous games and having harder puzzles.
