Huh... Windows only, it says.
Actually it says Windows to start. Then iOS, XNA and Android later.
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?
Because 90% of casual desktop/laptop gamers run Windows as their main OS?
Most interested people would be using Linux on the desktop and Android on the phone.
Linux users... are there any?? Android & iOS I agree. Far more likely to get casual users spending $2 or so on a game like this on a mobile platform than on a Windows PC
