Okay Winnitude , so I've replayed Demise and even had a couple friends play it with me so that I could get some second opinions, so here's my second review. First the looks; The visual fidelity of the models look pretty good. What me and friends don't like is your overuse of color within your levels. For example, the tutorial is slathered in purple neon and dark shadows that make platforms harder to see, meanwhile TheRift and Hell are burned with reds. This heavy use of a single color isn't visually appealing, and make the game look too saturated.
Next the movements: The movement feels rigid and clunky, and definitely takes a lot of time to really get a handle on. Momentum isn't reliable, especially the when utilizing the grappling hook. My friends really thought the grappling hook was counter-intuitive to what you were going for. This most recent playthrough I did notice that I can hold shift when grappling for a boost, which I didn't see before, so I apologize for that. Still, knowing that was there, it still took an arm and a leg to get past that section. The movement definitely needs to be more intuitive.
Finally the levels themselves; I was able to get farther in TheRift than before, even getting to the end of the level. Unfortunately the monsters kill very easily, and shooting them didn't give me much visual feedback to where I didn't know if I was actually hitting them. Hell is more straightforward by comparison, although the monsters seem less likely to kill you, which I found weird. Once you get to the bridge, you just get thrown around and it becomes a nightmare to play.
Overall I hope this is a better review, and I hope it helps you make the game better. My friends say Demise really needs a crosshair.
