I downloaded and tried out the Dark Void demo today. I had heard good things about the game, the premise seemed interesting and the whole jetpack thing cool. However, if the quality of the demo is anything to go by, this game is not good. Not good at all. 
 

*goes to download demo*

I can't say I'm surprised. This game hasn't looked good since it was first announced.

I had no problems with the controls other than the convoluted way they make you do barrel rolls.  You didn't describe this correctly.  You don't just use the right stick.  You HOLD down the right stick and then have to push left, up, down, or right with the left AND right stick at the same time in order to do barrel rolls.  It would be fine if it were just left and right stick at the same time but holding down the right stick while trying to move it left, down, up, or right is somewhat awkward (half the time I unclick the stick when trying to do it).
 
You hold down Y to burst forward in your jetpack.  I don't think you hit it twice.  You hit A twice to hover, tho.  A once to jump and then A again to begin hovering.  Hold down A to continue hovering upward but you have limited boost.  I found the lockon to be useless other than to see where enemies are.  It only seems to matter if they are directly in front of you and, since that is the case, there is not much reason to lock on. 
 
Other than these complaints, the air combat felt like most other plain games I've played.  The ground combat feels like ever other cover based shooter you can play as well.  Got your cover system, blind shooting, peaking out, up close melee combat, etc but with the ability to hover at any time and shoot guys from the air.
 
Overall the game seems decent enough.  The cutscene was terrible which gives little hope for the story.  It begins awkwardly and ends pretty awkwardly as well.  The tower seems to blow up for no reason and then the explosion on the plane was all blocky and ugly looking.
 
I'd say the most satisfying thing was the melee combat.  Hopping on to planes and hijacking them and smashing the robots faces in with your gun was rather good looking.  Think that shows that he animations are probably the strongest part of the game that I can see.  Seems like I'm the only one so far that would give this demo a passing grade.  While a little buggy at times, the gameplay was fun.

That sucks that it doesn't seem to live up to the hype set out for it. I'm going to download it tomorrow on the PSN, but if the flying controls are that bad, I won't be playing the full game. Which actually might not be so bad; we've got a lot coming up in 2010!

oh, i'll have to try it

Been seeing a lot of complaints very similar.  Disappointing, but not all together unexpected.  I'll check out the demo myself later.

Did not come away from the demo with much active desire for the game. Doesn't help that I've been in bayonetta land non-stop lately.

I tried the demo, for the sole reason that Jeff has mentioned so many times as something that could be great, and well ... not so much, the flight is terrible way to loose hard to lock-on the control is surprisingly stiff. on foot shooting feels weightless, guns feel like pea-shooters and the basic third person shooting combat with a cover system has been done better in worse games, i hate to say this but DARK f'ing SECTOR, has a better third person shooter feel, than Dark Void, very disappointed, looked great, a diffearnt setting but in the end bad design ruins it all.

Agree with most everything you said. The more advanced flying moves (where you have to press R3) were ridiculous. Once the terrible ground combat started I quit. I know it's a bad sign if I don't even finish a free demo.

Ugh, worst Jet Pack controls ever, having to press down the right stick and then move both the left and right stick in the same direction to perform a stunt doesn't make for good dog fighting, it is awkward and terrible. I agree the controls felt so wanky for controlling the Jet Pack. Glad I had a chance to play the demo, because I will not be picking this game up, the controls are just too bad for a game that focuses on flying.

The controls are so awkward. I hate it. 

Was going to buy, but now - hell no!

I just realised the pics I put up to go alongside with the text are terrible: they have nothing to do with the subject or caption at hand. I couldn't exactly see what was going on in the image gallery, so I just picked something with fire and assumed it was the jetpack. :p Dumb impressions write-up is dumb.
