A few major things were changed. While playing I noticed that Koishi's occult attack now rings and increases it's radius automatically without having to activate it. Kokoro's occult attack also received an adjustment so now you only have to counter once to put her in knife throwing mode and it lasts the whole match instead of until you get hit again. (Additionally, depending on the number of occult balls you have the knives will become other sharp weapons commonly associated with Kuchisake-onna like scissors and sickles.) They're might be other changes as well.
Also, has anyone had any problems getting the original .exe to run after the latest ver. 1.41 update? I've tested it and it seems to be a problem with the current version of Team Occult's English patch. It works fine until I apply the patch to the files.
