Divided

You wake up in Yume's bedroom with no memory of how you got there, and she seems oddly glad you're around. Fall asleep again and you land in another timeline entirely, facing another version of her: shier here, bolder there, but always some variation on the same woman.

The setup repeats itself across these shifting timelines, each one built around a different Yume and whatever unspoken history the two of you might share. Digging into that history, or just enjoying the company, is framed as the actual point.

You choose, each time, whether to pursue her or hold back and try to figure out what's actually going on. Those choices branch into separate endings, and the game is upfront that it wants you to go back and see the others rather than settle for the first one you land on.
