Nice game! The puzzles weren't too hard. And think of the cod not as a code, but as more like a translator. And for the box in DaVinci's room, think compass
Nice game! The curveballs really make you have to close your "field of view" since you cant predict where they will go until they are right next to the square. oh, and maybe some music that's not just the same three seconds in an infinite loop would be nice. 4/5
Definitely one of my favorite games. This deserves a 5/5. After you learn some of the tricks, it uses more logic rather than guess and check. I agree with jmdbcool, there should be a grid, and a way to "lock" pieces down.
