It's yet another doom clone.
Kill the enemies and get through all the levels. But be careful, don't forget the way back.
Controls:
Move: WASD

Feedback from the experts
Jupiter Hadley: The effects and graphics are super well done! I really enjoyed playing this, it feels like a complete game, though it does feel overly harsh that when you pick up a gem so many enemies appear in front of you!
