Alight

Alight is a platformer about a man who finds himself dreaming about his past. He smells smoke in his dream but doesn't know why... Alight appeared as a sponsored game on Newgrounds' home page in August 2011.

And as the story unfolds, it becomes clear that the boy is running from something deep inside himself, and seeking respite, whenever he can, in the heavens. Alight is minimal—requiring only a few movements and repeating its soundtrack on each level—but it's about as rich as browser games get...

If you have an hour or so, I recommend getting lost in the atmospheric music and playing through at least once... like me, you may even be tempted to return to the dream again to master all the levels and uncover the secret ending.

This game is a must play — it's so unique and the character's thoughts give new insight to one that may be going through these troubles from a different lens.
