This is a very colourful, fun little game. There are a lot of puzzles packed into a few locations, and a real onion-layered feel to the whole thing as characters' responses change and the game progresses. Building is all on the backstory of a previous game is a clever touch that makes me want to go back and play the earlier one (and I will). Characterisation is pretty good and the puzzles are not too hard and not too easy: I was stumped a couple of times, but the hints game to my rescue (they are well done).
I really like the introduction, and the sparing use of sound effect does enhance the game quite well. It's a shame they're not used more often in other games.
There are a few little bugs, but nothing major. I finished with only 15/25 so there is clearly more to do. I wonder if upstairs has any significance or if it is just a distraction? I'll have to go back and find out!
