Fantastic presentation, but mechanics?
Nice cutscenes (though lipsync was off and voices can be bland) and generally pretty neat visuals. Not always a fan of the audiosurf style technoscape stuff, but it looked pretty good and sounds were pretty decent. Didn't get far enough to comment on plot, so apologies for that.
Like everyone else, I think it is a bit hard for what it is. I *should* be able to decelerate if I really can't avoid something, so acceleration / brakes would be a good idea. Perhaps some powerups? If there's one powerful this needs, it's slow freaking motion.
Collision needs improvement. If you've gone over a boost, both barriers and boosts do not affect you. You can get damaged without touching anything directly - given the lack of a health bar, this is a serious pain in the ass.
Courses need to be more varied. Add a background, have the track curve and whatnot. The spastic techno doesn't do *everything,* y'know? One thing that might've helped a ton is having a dynamic perspective that follows the vehicle rather than sit in the same place - with the very twitch reaction controls, having an absolutely sure sense of direction is essential.
And that's my only real gripe. Difficulty due to mechanics. Hope to see some more good work.
