Thanks for the answers! Now that you say I remeber I had such a command for my monitor when was using Windows XP, but now I have Seven I don't know where it is. I will look deeper, it must be somewhere!

Anyhow playing windowed at 2x size is impossibe right? Even modifying some .ini file or something...
Thanks fot the hint about the bonus too, now I'm sure INT affects elemental arrows too I'll go for it I think

P.S.: The game is really wonderful! Have you drawn all this wonderful artworks for the graphic by yourself? I wish I had 1% of your talent ^_^
