I'll have to replay myself and do some rollbacking then to see what issues prop up, because it shouldn't really be causing any problems.
Oh, I wasn't seeing any issue with rollback in this game. I've seen it in other games, and seen other ppl & dev's comment that rolling back can/has caused issues. I usually just rollback myself, unless I notice it causing issues - in this case just to ensure no corruption/issues with what I was doing, I reloaded rather than rolled-back.
That is a very interesting bug, so it just went straight to Kumi after you answered with Hentai or did it skip some dialogue?
No, it played on as normal. So Mana responded to whatever I said, finished up and said bye to the girls there, and then got the Kumi scene where she asks if you'll come with her to visit her mom as hospital with her.
What happens is that scene gets to where she says "But I'll see you tomorrow ok?" and instead of moving on to the 'you get home and go to sleep' scene it instead then cycles back to her starting comment of "Oh hey. What are you doing out here?" and asks you again if you want to go with her, but this time the scene actually ends after she says that she'll see you tomorrow like it should.
lol yeah, it might be a little unfortunate to be mean to Mana in order to get a private tour with Kumi, but I did feel like it makes the most sense going by how Mana acts around people. She's not the type to hold a grudge or hate you outright if you don't like the things she likes, but if you start telling her to shut up or kill herself, she might reconsider showing you around.
To be honest, in just the little bit we have here, I can see that aspect on Mana, and how she is around ppl. I'm prolly just gonna have to resign myself to getting Mana tours if I ever need to replay, cuz I am generally not a mean nasty person and disliked telling her she was stupid (which is ironic, as she's not even a real person. lol).
And what, characters aren't 1 strike and your dead to them? Pffft... how unrealistic... /s lol
Seriously, I agree with what you said in the spoiler. While some ppl might be unforgiving, most ppl for the most part will let some nonsense go without too much grumbling.
As for the rest of your feedback, I'll fix those minor bugs straight away and I seriously appreciate you finding every single thing I missed. I've replayed my game hundreds of times and there's always a something I might not notice like an input not working properly or me forgetting a variable/keyword that should make sense given the context.
Dunno if I found everything
But you're welcome. I'm liking the game so far, and if I do find anything else, I'll post here.
