With a simple but effective decoration style, consistent and fun gameplay, and an amazing atmosphere, Marathon is a must-play for any fan of memory levels. As an entry-level extreme, Marathon will put your endurance to the test, while making for a memorable and fun experience. The main fault with the gameplay is the awkward chokepoints randomly scattered throughout the level, like the ones at 27%, 33%, 46%, 57%, and 67%, but if you master these timings it will be a smooth and satisfying playing experience. The level looks much more intimidating than it actually is, as I can assure you that you'll be able to play it blindfolded in no time, such is the consistency of its gameplay. The decoration pairs incredibly well with the song, creating a feeling of progression throughout the entire level, with an amazing climax at part 23. Less is more, and Marathon puts that concept to play as few levels can.
