The wait times are very harsh all around, as has been mentioned here a lot. And the main way I can tell to reload saves is by dying or finishing quickly, and both can take a lot of time if you want to redo anything. Or the confusing secret code saves, which seems like you have to get the code by going back to the main menu (only way I could figure out how to do that is closing the game and reopening). And of course, starting the game over or figuring out the part to skip to if you got far enough is still also very time consuming. You can skip story when you start a new game, but even that isn't clear how much it helps. All the waiting threw me off, and I was ready to quit, but I stubbornly wanted to see some things, then it started growing on me. As you've already mentioned, yes, I would love to see something done about all the waiting, but if possible, having additional menu options would help too like saving and loading, even if that has to do with secret codes, just easier ways to quickly access that information to redo parts you want without more waiting or reloading would be greatly appreciated.
Now I did beat the game several times, but I still only have 10 endings out of over 100, and I'd really like to see some of the other content I'm confused about. Like the incest content for instance. I would not even know it has any if people didn't mention it, and I have no idea how to find it. Also, trying to check ending hints keeps getting me stuck on the screen of the character I'm looking at which is very annoying and doesn't help me because I need to restart the game, but also doesn't let me know much about the characters I haven't seen. Anything for clarity regarding how to find things in this game would be much appreciated.
Last but not least, just wow! Despite some of my frustrations with this game, this has an impressive amount of content and, although I disliked it at first largely because of restrictions and forced waiting that consumes a lot of time, when I stubbornly persevered through it, it had a lot of parts that I wanted to keep exploring and looking into! Despite its problems, I have really enjoyed what I've seen so far! I do think if you can get past all the waiting, there is a lot to enjoy about this game, provided you have some time to spare. I do hopefully look forward to some improvements so I, and others, can see so much of the good this game does have with less frustrations getting through it.
