Great intro video, very engaging and informative. The game itself is very polished and fun to play, the character movement based on the character's rotation is a bit disorienting, but that didn't keep me from having a lot of fun!
Edit: I finally beat it, the game is really addictive but also very hard x)
I notice that they were some neat interaction, like friendly fire, and if you shoot at your ally they then start to shoot back at you, I don't know if that was planned but it give even more appeal to the game. Very impressive entry :D
