Really good short story experience. Basically this year's Journey. However I enjoyed Journey more. The themes being presented here didn't connect as much to me but I was able to understand them easily and can see how others would be more affected.
I really liked how the end played out using game mechanics to play into the growth of a character: spoiler (click to show/hide)
By pressing the big brother button you're basically invoking the "spirit" of big brother to motivate little brother to do things he previously couldn't, like swimming.
def thumbs up. really beautiful game too.
