GOOD NEWS! I was playing the game the whole day and I fixed all the serious bugs.

Ultimate Fix:

I also prepared saved files:

Save04: before the first boss.
Save05: Episode 2, just go to the bed
Save06: Farm finished, just try to leave

IMPORTANT: Saves files are saved in the game folder instead of appdata folder.

Sorry for the inconvenience.
