Imagine if you will that an encounter with your partner at an ice cream shop could lead you to question the very fabric of reality. Sound unlikely? Well, that's what happens to Greg, the protagonist of Lost Echo. A casual meeting and a flash of white light later, and suddenly he is the only person who can remember his girlfriend.

That's just the start of the mystery, of course. We'll refrain from discussing further as the plot is one of the main things the game has going for it. The ideas are intriguing enough, and the futuristic world setting is a marvel to behold.

But even for an adventure game, Lost Echo is painfully slow paced. The dialogue scenes seem to last forever without imparting much entertaining or useful information. This dirth of excitement is exacerbated by the slow speed at which you amble around the environments. You can run by double-tapping, but command this isn't as reliable as you would like.

Lost Echo is a pretty streamlined experience. If you pick casual mode, you can press two fingers on the screen to uncover hotspots, which is useful if you don't want to spend your time hunting for interactive pixels. Sometimes games of this nature can become confusing, but here, your next step is generally spelled out fairly clearly. This gives you relatively stress-free experience, but the lacadaisical pace at which the stroy unravels does undercut the interest factor.

And it's a shame, because the environments give you a great snapshot into a beautiful world. The lighting and clean-cut look of the architecture evokes memories of Mirror's Edge, where a shiny exterior is hiding a darker reality under the surface. If you can stomach the slow pace, advneture game fans should feel right at home here - especially if you like a good mystery. We'd need some snappier pacing and better characterisation if we were going to recommend it to anyone else, though.
