This is slow, barely interactive, and can only do full screen or a TINY box if you have a resolution anything above a pocket calculator.
However... this exudes emotion, from near the start to the end your mind will come up with theory after theory of meaning and cause, but you will likely not be correct.
If you have any emotions you will most likely feel it in your chest at some points. especially at the end when you realise it's still just a lie crafted from memories, you'll however justify that it causes a man to die happy, one who lived a life well deserving of it, and it's what people who cared for -him- would have wanted.
Buy this, it takes a bit longer than a movie for less than admission, it's about as interactive too.
Also.. if you play this, at the last ending scene, on the bridge - there is an easter egg, the signifficance of this is mindblowing and utterly fucking horrifying all at the same time.
