The game is excellent. BEWARE The game features an autosave mechanism without the ability to manual save. It does not create any backups, and the actual and only save file can be easily corrupted. Make sure you backup your save file often.
The game is a solid adventure game, with an interesting story, good puzzles and graphics. Compared to the first game, the developers tried new ideas and most of the changes don't really worked out well, but it is still a good game. If you enjoyed the first game and like point and click adventure games this is a very good choice.
