The animations are incredible and look very natural.
The rest of the game… I mainly had a hard time trying to figure out how to damage the enemy without being hit yourself. He has a longer range, a vaster health pool and hits you almost every time you come close. It might be better if the enemy followed a set pattern which left you an opening in which you can safely damage him. When he's unpredictable, you have to rely on luck or cheesy tactics, which is frustrating.
Shooting from your weapon also doesn't seem to do anything. And you can still move around and jump after your health falls under zero, with no way to restart the game.
And currently, since it's still in development, the environment around the characters sucks.
It looks promising (especially the fluent animations), but so far the game isn't really enjoyable.
