I'd not heard much about this game until I downloaded it recently on PS Vita from the PS store.
Awesome, awesome little game. I'm more of an action gamer and have never been that interested in puzzle games but this really is something special.
The first thing I love is the game world and the visuals. It all looks very Alien / Prometheus which look amazing but the game mechanics are a blast.
Stranded on the planet, you have to use a cloning device to replicate yourself and use your clones to help you explore the world you inhabit. You can also switch between your original body and your clones in order to open doors, cross gaps etc. But there are limitations and restrictions and each area gets tougher and tougher as you progress.
Highly recommend this one.
