That was different with the price of 2.49$? We're talking about 1.50$ here. I have offered the game for 2.49$ since V0.8. Now with V1.0 I think $3.99 is actually quite fair considering you get a Steam key with it. So I don't see how a price increase of 1,50$ disadvantages someone with disability problems? Could you explain that? I really don't get it.
Of course I am also planning sales. But I'll have to coordinate these with Steam in future because of their terms and conditions. It's not that easy to offer your game fairly for everyone on several platforms.
