Tests your brain to the limit.
Beautifully crafted game. The drawing and design was immaculate, and sound quality was excellent (for something that relies so much on sound, it would have to be!).
Anybody about to play this game, I will warn you: It can really screw up your eyes after a while. It is a game that will test your ability to memorise different solutions to problems, as well as your ability to keep your concentration, and not get distracted.
The one point I would make which would have made this perfect was that in the later levels when the music builds up, the drums can overwhelm the sound effects, making it more difficult to hear the sound effects (especially if you listening for incoming riders and their horses galloping). Other than that, absolutely brilliant.
