So I completed it last night.
I really liked it, it was beautifully made, looks amazing, plays well, has nice mechanics and lore. A real work of art. The scenery is fantastic.

Only bad thing is that it was far, far too fucking short. The quality makes up for it but yeah far too short.
Undecided on whether it is worth paying for. Quality says hell yes no doubt, but 14 hours seems...lacking for a game with no multiplayer. Although high replay value...yeah I'm not sure on whether to recommend buying. Definitely a game everyone should play though.
