This game was pretty good. It does a nice job of combining audio and visual queues in order to lure you along through the artsy world. Which is full of decaying modern cities and fading ruins.
I do think that this is sort of missing something though. Im thinking it might be some level of interactivity. Which a lot of artsy walking simulator esc games tend to do. It wouldn't need to be anything crazy, just maybe a couple simple puzzles, a switch to activate a neat looking machine, and you'd be good.
Again I thought Wonders Between Dunes was pretty good. It didn't blow me away, but its a strong contender in the world of visual exploration games. It just needs that little something to push it over the top.
