I really enjoyed this game. The twist is a tad predictable but I think that's more a testament of how effective the game is. You can tell something is wrong from the start and the more that feeling of unease continues, the more the game justifies your decision to not be fully on board with the events that happen in the game.
Its a game that does hit a bit close to home for me. Maybe that's why the game resonates with me as much as it does; especially the true ending.
Overall, you did an excellent job with this game.
