Great use of glow effects!   All those streaks for hot light make a nice contrast with the cold, desolate setting.

Definitely a challenge managing the horde, especially with the slow reload on the rifle, but I actually found that helped elevate the game.   It made it more than just a routine shooter.   I found myself thinking a lot about how to lead the enemies with the flare gun and exactly when and how to maximize the impact of my rifle shots.

Fun story too.  I like the surly pilot, although despite everything he said, I'd still love to have gotten out there and explored that castle a bit.  :)

I had difficulty sometimes taking down the enemies with the flare gun.
I tried aiming in front of them and behind but either some enemies have a ton of health or the hits not registering corectly?

Nice take on the theme.  I didn't get how the rifle cooldown works.  Seems like there's a timer but unclear when it has been reloaded?
