also added a few bits and pieces in other places
i dont know how to fix your platfrom levels you are trying but they are very broken. Anyone able to help ? Also Ninja enemy tries to attack when out of range, why would it do this ? doesnt engine know to only attack within range ?
i also updated your openbor as you were using an old one (now can stretch screen and add bilenear filter.
in Narutos character folder ive unpacked a Naruto from MUGEN which you may like to use insetad as has more animations than one your using (has good special moves)
I was going to add a death screen flash when Naruto dies, you will see it in sprites folder.
Hopefully this helps you try new features and get a better understanding of Openbor. Dont forget to download the manual if you havent already.
