After Years in a Dark Tunnel is about the preservation of hope in a dire situation. It has a prayer button. Most likely your prayers will not be answered, but it may give you hope. It also has a suicide button, for when all hope is lost.
It's the first game by Cosmic Maher, and it's a strange experience. After crashing on a desolate planet you go in search of your crew, but most of them are corpses. Eventually their corpses will appear to you as ghosts.
It's one of the darkest and most engaging flash games I've ever played. Just lay off that 'Q' button. Stay strong people! Life is worth living!
