For anyone that might want to buy a copy:
It;s $5.09 USD right now for ther Humble Winter Sale. Regular $14.99 ($16.99 canadians)
I may also buy 3 copies and prize them off.
Humble is an indie version of steam store. 100% legit. Not a key reseller like G2A. I believe you can also donate part of your purchase to charity, but that may be just a bundle thing.
