Like most modern adventure games, the puzzles were easy, however they were not hidden-object-game-easy, and I had to use the in-game hints couple times, so it was playable.
The art was very nice. The story ok too. The use of ghosts to solve problems made it less than intuitive at first.
The real downside is the dialogue. Ugh! Reads like a 12 year old wrote it. Some character says something ... silly ... and another character says some version of "shut up you moron". Well, don't write it in the first place, LOL! I'd give some examples but that would be spoilers.
The bonus chapter / extra quest, that you get once the credits are done, is really nice though. Better art, plot, etc. Wish the whole game could have been like that.
