I've enjoyed the MCF series for a long time, and I play them at the expert level for more challenge. Eipix-produced games were becoming unchallnging, as even in expert mode the cursor would change to a hand over a retrievable item, or gears where an action was needed. Not so in this game, and it adds much-needed depth to the gameplay. Graphics, puzzles, and H.O. scenes are sweeter than ever, but more variation in the background tunes would be nice.
