The look and feel of the game is really appealing. I definitely could have played for several more levels, with puzzles of ever-increasing difficulty. The music and sound effects presented a unified design. How I got my cube's color to reset was the only confusing part; I often just rolled around and rewound until it eventually did, but I could never make it reset consistently (or, does it just fade off after a certain number of moves?) Perhaps that bit could be clarified, but otherwise, a great game experience.
