Hey thank you so much for the info but we have some bad news: the log says you're using OpenGL 1.4 while the lowest compatible version for Unity is OpenGL 3.2 and up. There is no way for us to lower the compatibility, at least not to the version you currently have... which kinda blows because we were hoping to have the game run on old hardware but it seems it at least needs OpenGL 3.2+. There doesn't seem to be a workaround except upgrading. I'm really sorry but I hope there's a way you can update your OpenGL without the need of a graphic card.
Oh =\ well, that's ok. I can't buy a graphic card not even a new pc now cause the prices here a very expensive, I had the bad luck to be born in Brazil XD
But anyway, thank you for all the patience you had to try to help me, I appreciate that. And good luck to develope the rest of the game, it looks great so far ^^ I wish you all the best :)
