As it started I was reminded of perfect dark/golden eye on the N64. In a good way =D. It's really well done with attention to details like not picking up health/ammo if you're full. There is one issue of the enemies not being able to jump and they get stuck. Also in level one it's hard to move past the massive crowd of enemies as they can attack from below. Overall it's a cool little experience with some good enemy AI programming.
