Ephemera  is hard to put into words, it is a strange type of game.  I believe their own words will do a better job, check out their summary then trailer below-

She leaves at the end of the summer. You only have one opportunity to shape your memories of this fleeting relationship — or instead, seize these last few moments together as they unfold.

“Ephemera” (“Les éphémères”) is a narrative experience in which your interactions impact how you seize and remember the world around you. Reveal impressionistic vignettes of your final summer together by painting them with ink or capturing them on film. Take part in an intimate second-person narrative entirely voice acted in Quebec French.

An interactive take on the tale of time, memory, and loss.
