I've enjoyed the full Guttersnipe sequence of games; they generally feature well-thought out puzzles involving an urchin doing ridiculous things and eating junk.
This game puts a spin on things by placing your long-standing help system and narrative device Percy the Rat in confinement.
It features stereotypical Italians as the antagonists, with names like Tony Macaroni. It would be somewhat uncomfortable, except that it's less of a parody of Italians themselves and more of a parody of gangster movies's and novels' parodies of Italians.
There were several bugs in the version that I played, but it made the game more interesting, as I had to type exactly the right command, and it became just another puzzle. But polish and interactivity correspond to two of my stars, which is why I'm giving 3/5.
Edit:
Since my original review, the game has been revised to fix many bugs, so I'm increasing my score to 4/5.
