New version in beta with easier difficulty and "Visual Novel Mode"

Hi all,
since some people asked, I uploaded a new beta build (as usual, right click on the game name, choose BETAS tab and enable beta branch to try it).
The changes are:
- updated the game to latest Ren'Py
- tweaked the Easy difficulty level so you get +75HP, this should help people who had problems winning even in Easy mode
- added an experimental "Visual Novel Mode", which will automatically skip all the battles with an "instant-win", useful to replay the game to get other romances or for those people who only play for the story! ;)
