So here it is.
I started with the original stage demo which we've all seen and the first thing I do is try to get used to the new set up, tryed out some combos, shot the guns for a significant ammount of time to see if they over heated, they did not, and, unlike Bayonetta, once you start shooting in one direction that 's the direction Dan shoots untill you stop. I walked and shot in all directions and the animation was a faster version of the walk and shoots of DMC1 and around as fast as 3 (don't remember if it's the same as 4). Another thing I noticed was that the game is not as well made as DMC4 in terms of visuals, now that I've seen in in action on HD, polygons and sharp edges are obvious on some of the lesser characters and the shading and texturing don't come off as smooth. So in terms of estetics DMC4 has, still, the best graphics
Since the line was so time consuming and I could only play once I decided to try out a lot of things, might as well.
So we get to the first fight and I put out a few combos. I try to switch weapons mid combo which works fine but even if the combo is the same botton sequence switching weapons restarts the combo so no mixing and matching weapons even with the same combo (chocolatepanda, is that what you were asking?). The dudge works fine but because of the timing of the attacks I ended up taking damage do to the fact that I'd dudge too early. The switchig is seemless, though, so no worries there.
The way the Demon and Angel forms are set up are somewhat counter intuetive when you actually get your hands on it. This is provably not an issue for anyone starting out with this game but as someone used to the original set it caused alot of issues for me.
Anyway, I tried out a few things while moving around. I tried to see if the wall would really crush me if I stayed in place on the last part before the church, they do close in on you. When you see it on a HD screen you can seen it slowly moving in on you, which wasn't as obvious on internet videos, but even if you are crushed in the demo there is really no penalty for it; no health decrease, no death, just start from the same place and the game might give you the impression that speed is of the essence but it's not, pleanty of time to hang out before you have to go. The movement of the city is constant so even after a big change or crack or bang it still moves slowly. The music and the slowly moving world gives the sence that you need to move, but again, it's not urgent as you are been led to believe. I was tempted to walk, and I did afew tiimes, to see if I'd die... Nope. I moved to the church and finished that.
i started with the boss fight and I can tell you that it's actually fairly challenging, even with prior knowlege of how to beat Poison. I managed to counter her swings fairly easily, it's not as hard as I thought it was going to be. I left her dangling once to see how long it would take for her to recover, not as long as I predicted, but enough to get to another plataform or two if need be.
Overall, it was the same demo with no surprises in terms of content.
Now, f you'll give me a minute I'll type up some more specifics.
