Hey Happy is an interactive narrative made in Unity. The story is told through a series of letters. Each letter corresponds with a miniature 3D scene. Within each scene, there are collectable objects that must be found in order to advance to the next. Click on the objects to interact with them. The relationship between the two correspondents progresses with each letter, although the vague style of writing leaves the narrative up for interpretation. The scenes are momentary snapshots of locations where the characters have spent time together in the past.
