Here's an idea for four achievements.
Medium: Get to the first purple checkpoint.
Hard: Find all the artifacts.
Hard: Complete the Game. (This can be done on any difficulty setting)
Impossible: Complete the game on Expert. (Probably the hardest impossible badge on this site.)
The part where everything gets explained in a long dialogue annoyed me. This is not good storytelling! You're supposed to weave exposition into the narrative, not hand the audience a f*cking glossary as they walk into the theater.
This is probably an odd thing to pick up on but when I got Clarence dressed his footsteps became very loud. It was as if someone was banging cocoanuts together.
So apparently that blue text says "She has no soul, do not trust her." Are you trying to manipulate us into getting a bad ending in the next game through subliminal messages?
You seem to be phoning it in on most of the levels. They seem to be the same environment copy-pasted with a different relationship element on each one. I can only give it an average thanks to the story. If it didn't have a good story than I would have given it a much crueler judgement.
I thought that their would be differences in the story or at the very least a harder final boss when I replayed the game and chose not to warn Last Flake's clan and help the priest. What a wasted opportunity.
Why do people keep confusing infested with infected? Infested means being inhabited by a parasite. Infected means being inhabited by a virus or bacteria. Parasite's are multi-celled organisms while viruses and bacteria are single-celled organisms.
Events seem to have the mark of bad storytelling since the whole plot is reliant on a single coincidence that some clumsy soldier coincidentally dropped an egg that coincidentally landed in Eva's hands.
