Overall, ECHO: Secrets of the Lost Cavern is a solid entry to the adventure genre. The puzzles are thought-provoking and the story, if not the most refined, is at least interesting. It is beautifully crafted, with only a few noticeable issues. If there were one real flaw to the game, it would be its length – it's too short! It was over somewhat abruptly, and I found myself wanting more. I wish there were more entries like ECHO to the world of gaming, and I wish more titles such as this got the attention they deserve, but that's just me.
