The environment is pretty great, I really love the skybox and the scale, it's simply awesome. Whole game definitely has a twilight zone story feel to it. The flavour text on the enemies is a nice touch, provides a lot of intrigue.
Interesting story because I was definitely ready to side with the aliens on this one. Gameplay loop is pretty straightforward, with some very minor confusion about what all my HUD sstuff does.
Congrats on the release.
