I just downloaded the 9.1B and I have to say a few things:
The games feels way slower and heavy then the previous release (I was playing the 0.8.4B before), at least on Mac.
I tried the erecto totalus,but it does not work. I only get the options to reset game progress.
Do I need to replay the previous chapters to unlock Ginny's Act2/Chapter2 scene? Or I can start from the latest chapter and still get it?
I'll rather restart the game from the beginning if I can't access certain scenes or if I can't use cheats to regain the money and stats that I had in my 0.8B save file.
