Wow.. Im surprised. I was considering this when I first saw it. However, My problem was that the first "donate enough to get a copy" tier was 20$ and it indicated it was redeemable by Steam. Given Steam wrongly demands to forfeit legal rights, this would be completely illogical. So I thought, Hey I might consider, if they were to break the tier to allow for Linux Support. However I simply didnt think this was going to muster quite that much support. So I stopped following it. Now that it has, I find myself just broke enough for the month I cant afford to donate now.
Oh well, my fault. But, its good to see that much support for it. Wont hurt to get it once its finally released at full price.
Just wish they would get a tie in with GoG given how disgusting and vile steam is.
