I am investigating a refund.
I have several hundred hours and I've had enough of the problems.
I don't know if it's possible to get a refund with hundreds of hours invested into the game, but i was able to get a refund on steam with over 20+ hours of gameplay by choosing the option "doesn't work" (or something similar) and putting a link to this thread on your ticket, along with whatever other proof you have.
I guess the 2 hours-14 days policy only apply to buyer's regret, so it's worth trying a refund when the game is broken.
