Gameplay:

Solid puzzles and a good storyline, backed up by strong and beautiful scenery.

Graphics:

Adventure titles always do well on minimal hardware, since they're not having to work so hard to present an environment. Still, Echo's environments deserve accolades for being simply beautiful.

Sound and Music:

Someone took their time casting this game, and it shows. The simpler music with early-sounding instruments fits well with the time period the game is set in.

Difficulty:

The puzzles can be a bit more difficult than some games, despite the relatively low number of objects to manipulate.

Controls and Interface:

As adventure game controls are pretty well set with mice these days, there's not much to tell, but it's still a simplified interface that does well allowing the gamer to explore without getting in their way.

Overall:

A decent story and fun game suitable for all ages. Worth playing together with your children, if you have them. The added bonus of the documentary section is a nice touch.
