I'm sad to say that the demo just didn't catch my interest.

I was on an Android 4.65" phone and found everything to just to to small. On a computer or a 10" tablet it will be playable I'm sure.

Movement on my phone just wasn't good. Aiming was a bit hard and I easily got killed by the first creature I met. Controls are very hard to get acceptable on a phone which is why I prefer turn based games on it.
