"If there no solution exept by a new computer, forget and keep the money for creation."
Now I'm pretty sure I know what the problem is (basically we were planning on making the build more friendly to older machines but didn't get around to it), but how awesome is it that they still wanted to help us fund the game, even if we couldn't get it working for them.
This is why I make indie games. For the people out there like Fabrice. There's an awesome community out there that supports us, and I want to make kick ass games that they love to play. Thanks for making my day Fabrice, we'll get you up and infecting soon!
