I finally gave the game a chance despite my original plan to wait for potential official, or at least attempted human fan, translation, but I can't open the settings. It plays the jingle sound like it would when opening the menu, but nothing happens besides that sound. Other than that, no issues. The volume settings are the biggest issue, I need that menu to deal with volume settings as I typically lower any music or ambient sound that isn't handled by the voice settings so I can hear when a girl is near. It was a trick I used in the original Koikatsu when looking for specific girls since they all had different sounds while walking even if they shared some of them.
EDIT: Okay, it WAS my only issue, just came across another one I haven't seen since AI Shoujo. I was talking to a girl and I was suddenly left with no options. The only difference between previous talk interactions and this one was that I had prayed before at the shrine and gained the "ask for sex bonus" as it is called in Cheat Tools as well as cheating 100 points. It isn't frozen, she's just staring at me with no way out of the conversation and no way to move it forward. The music is still going and so is the scenery behind her. This MIGHT be a bug that Illusion would have to patch, possibly in the bonus I gained or the actions it is meant to be a bonus to, though this bonus sounds more like something I have to start an action to use, not one that triggers from something she does, so it shouldn't have been the bonus. It could be the points I cheated, but again unlikely. I CAN exit the game normally, but that is the only normal function I have when it does this. I'm going to try from my autosave to see if it was maybe something I did.
EDIT2: Also having a crash if I rapidly toggle the teleport menu (F3). I didn't do it intentionally, my fingers occasionally bounce on the keys, causing a double press, which in this case toggled the teleport menu. I'm going to give this another couple versions to see if there are any fixes in any part of the repack.
