Pros: Offline; Cultists can blow up due to shot which is giving brutality to what is happening; Good optimisation; large shot spread, enemies shooting from everywhere and their large number forces you to act aggressively; There is time dilation (Right Click); Killing enemies replenishes health; Even death is not very frustrating, since you can start from the beginning very quickly thanks to the quick start button and a small map; Enemies sometimes try to climb onto rocks and start jumping over them right towards us, adding fun to the game.
Cons: The game is short; Even the "Lunatic" difficulty isn't enough for full-on action; The difficulty of "Lunatic" lies only in the huge damage to the character; The parkour level is not funny due to character's speed.
P.S.- Sometimes I walk into this game on "Lunatic" without time dilation for bloody fun and action. I can recommend ideas about temporary boosts and new enemies, but I think that the author has done everything he can, so he deserve a break
