Ok, i finished the game.
I'll say to this : "no comment."
I don't like giving bad reviews, avoiding the little things which doesn't go well, but i'm sorry, i can't pass it this time.
The game is awfully short, i spent "almost" 3 hours to complete it (and without skipping). It took me ~1.5x more time for each other episodes.
There's only 5 "locations", the investigation is close to none, the game is composed at ~90% with puzzles.
It really breaks the game immertion, to repeat them over and over until i found the logic.
The story flow is kinda erratic, I moved from scene to scene sometimes even without knowing why.
Unlike the other episodes, all the Erica's and Cordelia's puzzles are completely useless and the way they are done makes the game completely linear.
Lack of inspiration ? At least in the other episodes, when i was stuck, there was still something else to do or "try". Here, nothing. I have to do the puzzle to go to the next puzzle, which will unlock the next puzzle.
Wow, really, you have disappointed me. I wasn't expecting an episode as bad as this one.
And the ending. Incredible. Even Cordelia's last actions are illogical. But since you wanted to finish the Season one's story, i can understand you had no choice but to rush things.
So here's my final notes :
Episode 1 : 13/20
Episode 2 : 14.5/20
Episode 3 : 14/20
Episode 4 : 4.5/20 (there's no number missing !)
