This was the final episode and I thought it was fairly flat. I suppose I'm spoiled on the game's story, but I don't care much for the way they wrote the story in the final four episodes.
Episode 11 left something hanging at the end that was never brought up again. It was as if the anime producers planned on going in one direction, but then changed their minds and went the other way instead. What the heck was that all about?
The next episode was a "compilation episode". It summarized what happened earlier in the show, but there didn't seem to be any reason for them to have it because this series is so short and there wasn't any reason to know what happened earlier.
Making up imaginary reasons why they might have produced it:
1. The anime makers found they had less money than what they budgeted for so they decided to save money.
2. A major problem came up and they decided to discard what they wanted to do for episode 12 and have this compilation episode because of its LOW cost. Without the continuing build up of tension in the discarded episode, they made the ending less dramatic so that final girl's events wouldn't appear to spring up from nowhere. By doing this they also leave themselves open for a second season. The problem with this imaginary theory is that the anime already went partially into the final girl's game ending story and if there's another season they would have to make up another ending. (Made up filler story. Oh boy.
)3. They wanted fourteen episodes so that they could put the series on seven R2 DVDs at two episodes each like the Kakyuusei TV series (thirteen episodes + bonus episode).
Whatever the real reasons are, this anime has disappointed the gamers. In the fourteen episodes of this show, we had two "made up" episodes and one compilation episode. That makes this (technically) an ELEVEN episode series. They didn't even do a good job at telling the final girl's story. Instead of her emotional, tearfilled game ending story, we got a scene in the anime that felt more like a misunderstanding (something that happens DURING the anime and not at the END of the anime). Oh well...whatever. That's life eh. ***shrugs***

Absolutely brilliant!! 
I'll probably watch another episode of this.
There were some enjoyable scenes in the closing credits. I suggest picking a fansub (like AnimeU's) that displays the "sponsor" opening and closing scenes with the ship Rin was building. They did something differently with them this time (the opening ship scene of episode 24 is similar to the closing ship scene of episode 23). I was sorry to see this show end because it was a pretty fun show.
