After checking the wrong hare, I found the issue since the LLM did truck with the code at a few points (using the Japanese period when it should be '\.'). I should have fixed them all. Otherwise please report with the save (if game breaking) or lines.
On the upside, I had someone (Gemini) make me a simple PS script for everyone to use to update the game. It's not as intricate as Dazed's so it will only work on Windows and I am not one to know if this could be exploited (I can't code for shit) so I can only say that you should never run a .bat you don't trust. Even if it looks nice you can look inside both .bat and .ps1 to see what they actually download and execute.

I also fixed the 'load' on the start screen which was not translated (the dev for some reason just had it lower case while anything else upper case). I can concur that the game itself is a tad disappointing (the boss not attacking seems to part of the JP version as well but it could also be easy mode) but there is a lot of H.
