Hotfix + Small changes

Some bugs were introduced in the previous update, which are now fixed:

• Alternate (soul) ending should now be properly reachable
• Both English and Japanese versions are now within the same game - you will get to choose your language at the start of your run
• JP版の小さな修正
• There is also a new(?) weakpoint-related exploit which trivializes some parts of the game, but it's not trivial to find or use and has interesting quirks, so I left it in. Have fun!
