Fix version 0.3

I have updated the links for versions 0.3 due to an error in the fight with the boss where when you were wearing the school uniform you could not leave the cave. I have also fixed some errors in the texts and a bug with the stat levels, and added versions for Linux and Mac but since there is no way to test them, I don't know if everything would work as it should.

thank you for continuing to support this project
