This game needs to be rated by more people! Very fun controls. Looks beautiful. I LOVED the intro with the other dead characters that look like you. The only complaints I have were bug/design related.
The game gets pretty hard but ammo and health is hard to come by. When dying, ammo and health is not replenished but enemies are reset. Which if this was a rogue like, would be fun, but I think you want your average player to experience the story.
I also had an issue with the bullets in the (assault rifle?) Sometime, I think when there were a lot of moving parts, the bullet would be stuck to the tip of the gun and not shoot out. I think this is a frame rate issue but I'm not sure. Also eventually my ammo froze and I was no longer able to shoot. Unfortunately I had to stop after.
Lastly, in the beginning, how ammo worked was confusing. Usually the number on top and bottom are handled like call of duty. Your way is more realistic but since it's not the standard, I would find a way to visualize bullet count better.
Excellent entry, just a few kinks here and there. Best of luck!
