To echo some sentiments:
Ideas are solid. Camera looks pretty cool. Visuals are good-great, depending. Battle has potential, but somethng's... wrong.
In short, I think the core of the battle issues are:
1) Animation. Stiff, stilted, disconnected from the world. Really needs work. There doesn't seem to be ANY power, or inertia in any weapon movements.
2) Enemy reactions. Due to 1, it looks like you simply cut through air near an enemy, and they slowly fly away, gravity free. Again, weight, inertia, and power aren't translated in this at all.
It's a mix of everything. The effects, the animation, the sound, and the enemy reactions.
Ah well, I think it's solid enough to be beyond the usual "omg canned lol" danger zone, but my whole gaming life hasn't been a lie, thus far.
