The story and the controls are ok. It's not a bad game but commit typical sins of 90's point&clicks. There are a lot of thing just can be figured out by try and error. There are some guessing and pixel hunting. If you miss an key item you need to re-explore every single location you have access.
From now on, I will call TB to "The Breakthrough" and HNE to "Harvey's New Eyes". This are the first 2 games from Deadalic I truly liked. I played before "The Whispered World" and "A New Beginning". I'm saving Deponia(I,II) for later. Both games still have some bugs after the Q3-2013 patch. I advice you a little research at GOG.com forums before buy. TB was one of the first games of Daedalic and you can see it for example in the controls. The controls are just good enough at TB, at HNE are better. HNE is a more polished work in general. Both games are dark and funny, being TB funnier and HNE darkest. Something I like you know before hand is Edna and Harvey are playable characters in TB and no-playable characters in HNE. The playable character in HNE is Lili. At fist glance, Lili is just a sweet, lonley girl. Through the game you will have the chance to know her deeply.
As other reviews stated, is too based on luck. In this sense, its remembers me "Faster than light" with a different subject, and no action. To make it clear, I enjoyed FTL much more than LLtQ. To survive certain events, you need to train her's skills several turns beforehand, and the game gives you no clue which one until it kills you. Then its become a die&load festival.
Syberia I & II should be one game. I'm wrinting this 'cos both games feel the same to me. I'd loved both. Great story telling, beatiful graphics, simple interfase and almost none pixel hunting. The only thing that bothers me in these games is the time spend in traveling through screens.
It's a great adventure. I don't know why it has mixed reviews. PROs: Beatiful graphics. Original and interestings story. The puzzles makes sense. No pixel hunting at all! CONs: Traveling from screen to screen could be a little slow and boring when you get stuck with a puzzle.
