Most overrated game of 2015.
Take a crappy bullet-hell style shooter, and mix it with pretty crappy puzzles, a quaint and occasionally amusing RPG and some clever ideas.
I had heard the ending was absolutely magnificent. Perhaps I missed it somehow, because it didn't do much for me, in fact I was more in disbelief that that was all there was to it.
There appear to be a bunch of different endings, if you're a completionist type... frankly I won't bother playing it a second time to see them.
