La Malédiction dont vous êtes le héros

In this French IFComp game, you see (in a linear hyperlink format) a teenage couple who are checking out the moon with a telescope.

After one playthrough, you earn 10 points that can be used to go back and change the story at 4 critical points, for a total of 16 possible endings.

The writing is well-done, but as another reviewer noted, it is repetitive, especially since you only get 10 pts per playthrough and any choice you make spends that 10 pts. You'd basically have to play the game 4 times with no choices in order to play the ending that uses all 4 point spending opportunities.
