SeaBed made me cry for like 20 minutes straight while trying to read it through tears. I've never really read anything else quite like it, and it seems to me that it's truly a shame that it isn't widely regarded as one of the best visual novels out there. Sure, part of what makes it so unique – the extremely slow pace, and a story that is mostly interested in looking at its characters through everyday conversations and the mundane details of their lives – is somewhat off-putting to a lot of people; so it probably makes sense that it's not that well known.

However, by the end of the game I personally felt like there was hardly a wasted moment in it despite how slow and relatively light on plot it is. All the time spent on characterization and building up the central mystery of the game was, to me at least, absolutely essential for the story of SeaBed to be so affecting and end so strongly. It really is a beautifully constructed visual novel, that's well worth reading even if its narrative structure is different from anything else you've ever read.
