It starts off quaint and corny and you'll need to adjust to the production quality, but the story really grows on you.
However, this game contains a gem of a story. It's cleverly based on L. Frank Baum's world of Oz, but with a twist: all known old characters and new ones alike now have a completely different character. But this is not an Oz story necessarily; the world of Oz simply functions as a backdrop setting, including its characters. The story has merit on its own that go beyond what you know about Oz. It's a charming story, with clever details and sometimes surprising. And when you get into it, it's easy to ignore the poor production quality.
The game mechanics are mediocre: you get some items throughout the game that are not too hard to figure out how they fit in the game and you can't combine items either. When you're stuck you can get hints until it flat out tells you what to do to proceed. There's another mechanic that sort of works like items, but I won't spoil it too much here. The mechanics are simple and straightforward, but they work to progress the story without making it feel like an interactive movie. The story progresses through 'quests', although you just get them handed over to you as you finish puzzles (think of puzzles in the traditional Point 'n Click sense: talk with everyone and combine the right things).
You have a certain degree of freedom, but you hardly use much of it. Especially later in the game your freedom is limited to two or three screens. This is no doubt connected to how the story progresses through the linear series of quests.
All in all a nice game to play and complete on a Sunday midday. The dialogue is proficient, the audio track seems to fit in, the drawing is mediocre but you get used to it quickly. The voice acting has its ups and downs and the game mechanics work though are not the reason to play the game per se.
The story is what keeps you playing, like reading a good book keeps you from putting it away.
