Well ... err ... it's heavily unfinished and it feels that way (lagging in some areas)(no criticism in any way but I was left unsatisfied).
Visually it certainly is appealing and I'm sure it would have been lots better than average. Enemy placement (although too sparse) is good: I was really surprised twice.
Unfortunately I didn't get any story feeling and without a goal it was more of an exploration session than a mission. I also didn't really feel the non-linearity you mentioned but did see quite some dead-ends (probably the symptom of it being unfinished).

What do you mean by that? Technically too hard? recahing the limits of the engine? or taking up too much time?
