Huh... Windows only, it says. Bad, bad mr programmer. A good game for a BAD OS I don't even have at home is not good!
This makes me wonder: I suposse (I could be wrong) most players who can appreciate these games are somewhat technical skilled, tinkerers, etc.. So why those indie developers choose Windows as a target? Most interested people would be using Linux on the desktop and Android on the phone.
Enslaved or captive Windows users are always consuming the latest technology, ultra-hires 3D graphics and all that nonsense.
