1. Ayame said she ride the snowmobile to the bridge and realized it was on fire, but doesn't this contradicts with the weather report? the game established that someone had to bring the snowmobile to the bridge while it was snowing because there is only one track. Am I missing something here?
2. I'm not really sure what's the purpose of setting up the fake murder scene in the main temple. After Godot kills Misty, why not just ask Ayame to drop the body after swing it over the bridge? Godot wants to prevent Chinami's plan, and part of Chinami's plan was to blame the murder on Ayame, so why did Godot have Ayame to ... set herself up?

I can't really explain that either, because it also doesn't make sense to me. I don't think the intention was to set up Ayame specifically, since they couldn't have known Bikini would walk into the courtyard and see Ayame with the sword. But it was a rather poorly conceived plan. They had to have known that in a sealed off temple, someone inside - someone innocent - would take the blame.

I always thought it was because it wasn't snowing when Ayame rode the snowmobile, and then it started snowing while the bridge caught on fire. That covered the tracks from before. Then when Ayame rode it back and made a fresh set of tracks.

I could be wrong, though.
