Root Letter's third trailer gives us a clue

Root Letter is definitely turning into one of the darker visual novels I've had an interest in, mainly thanks to the handy subtitles, even for the JP version. As long as Kadokawa don't give too much away before it gets here, as we're already on a third trailer.

I'm guessing we're looking at Steins Gate levels of depth to keep people interested, which is no bad thing. Out in the summer, it should be worth picking up.
