I bought this game at full price after playing it for free to completion to show my support for Supergiant Games and the unique experience that their games provide.

I didn't care for the 'combat' aspect; but the effort put into wealth of writing, art, music, characters and atmosphere drove my purchase, rarely do we get a game with the love that Supergiant gives to each of these aspects.

I rarely buy games and when I do they're heavily discounted, this is one of the few full price purchases I've made in a decade and I can count all of those on one hand.
30USD from one purchase doesn't seem like much but knowing it supports everyone involved in development give me no regrets.
