Luna is a short (~1h), beautiful narrative game about a little bird who has to bring back the moon. 

The main interactions are small constellation puzzles and sections where you decorate little areas with plants to bring life back to them. The puzzles are not hard, and there is no failstate. They are simple the means by which the story is told. The main point is to experience the story and admire the gorgeous visuals. 

The music is also beautiful, combined with the artstyle the game reminds me a lot of Gris. 

The controls are unfortunately a bit wonky, even after the addition of the mouse sensitivity slider, but it's not a huge deal. 

All in all, this was a great way to spend an hour and I heartily recommend this game.
