The Company of Myself is one of my favorite flash games, and I was very excited to see a prequel starring Katherine. (warning, spoilers)
The game-play was very interesting, I loved the smoke and lasers, they were fun even though getting the rings right is sometimes difficult. Also, the game was very apprehensive since I knew that Jack ends up killing her.
However, the ending is... iffy. I can accept that he just totally forgot about her; he's on drugs and mentioned earlier that his memory gets confused. But how did she die? Was he wrong about where the path on the right goes, or lie about it? At the end of TCoM, it seemed (to me) that he knew about what happened, but was I wrong? Does he never realize that she actually died?
The ending with Jack would have been fine... if it weren't for the fact that I want to know what happened to Katherine. That death worked for her in the first game, because it was all through his perspective. But right at the point where we lost her originally (I love the parallels in the last level btw), suddenly we switch to Jack. It's disappointing.
