Very cool -- nice use of lighting. Controls and camera feel smooth.
I couldn't tell if there was an ending though, I sort of just wandered around the map after defeating all the enemies.
Thanks for feedback!
There is no hard ending. You can unlock some doors and gates with consoles (the idea was that you'd be contacted by security over radio, and they'd advise you on how to progress), and eventually arrive at the hangar where a boss fight was supposed to take place (and an ending cutscene), but right now it's just an empty room with glowing text that explains how the ending was supposed to play out.
