The Trace may have been a little bland in presentation, but it was really effective in gameplay. Making you fully immersed in crime scenes thanks to a great use of your device's touchscreen, it ended up being one of my favorite mobile games from last year.
It went into the same category as The Room for me, a tactile experience that was over way too soon.
If you didn't get it when it first launch and if you have an Apple TV, you'll be pleased to know that it's on sale now for £1.49. Sadly this version is not universal so you'll have to purchase it again if you owned it on iOS.
