I liked it.
The game plays very smoothly, and the controls are easy. Just, it i Mafia, then maybe I suggest you put instead of Birdo, at the end of stage one, well, maybe some mafia guy, or at least Birdo in a mafia costume.
This is a great idea. Don't get me wrong, I like it, great game here, just get closer to the idea. Mafia Land with gangsters, but I completly enjoyed the rest.
