Man, I really don't want to be negative because I REALLY do like this game ! But that last stretch from C2 to C1 is just impossible for me. I don't see how you're supposed to juggle between warding off the light sensitive enemies and the sound sensitive ones with how frequently they spawn. I don't even know how the optional spare generator is supposed to help ! Maybe I'm just too tired from trying to see how you're supposed to do it...
But other than that, I like the concept of the game, the story, the characters, and aside from that last part, I did like the previous two difficulty spikes.
The game IS good. Just too overwhelming for me, perhaps.
