You don't have to rush - Zeno Clash will still be -25% until its release in about a month.
Nobody can really answer your questions - the review copies aren't out yet.
Look at this video and see if this is something that appeals to you:

I'm really curious how the combat will work in practical terms since I'm a big fan of it when it's properly executed, while many FPSes have failed to make it interesting (e.g. Dark Messiah of Might and Magic :-P). If it's anything like the system from The Chronicles of Riddick: Escape from Butcher Bay, only with some additional options, then count me in! I also dig the crazy artwork - finally something original - it may turn out to be pointless but at least it shows somebody tried, unlike in recent big-name shooters that always feature similar artwork and even story lines (compare Resistance, Gears of War, Killzone - all good games but VERY safe in their design decisions).
