Sorry about the awful late reply. I didn't see the notification. Performance and stability vary a lot depending on your phone's hardware. A quick search says it has very little RAM compared to what's the standard these days. It should be enough to play the game, but again, it depends. Try to close as many apps as you can, to free up some resources.
Yes, you can copy your save to your computer. Read a little above to find where are locations of the saves. All you need to do is copy and paste.
The gacha is something completely unrelated. She wants a Sunday event. The hints of those are on your page. You're probably lacking Hibiki's love points to trigger it. Take the girls to the beach/pool and pick her as much as you can.
Can't really say. It's already taking longer than expected. Health and other IRL stuff slowed down the development. Hopefully, it won't go past next year.
For Suzume, you need to go to the pool 5 times and each time you have to talk with her (make sure to spend time with your girls before). No porking Erina yet.
I'll see about that, but the achievements are pretty straightforward. Meet the girls, lewd them (BJ and sex) 15 times each. And complete events, like the beach one, the pool one, and so on.
* Pick every girl in the repeatable beach event, at least once * Bang everyone in the repeatable pool event, including Suzume * Bang the three unique Aurora clients, Manami, Sayo and Shiori
The game is made in a way that you won't miss anything, so no worries of doing stuff in a specific order, or stuff like that. There are no timed events, time limits, or similar. That said, the game focuses on intertwined stories, so you can't just focus on a single heroine from start to finish. You'll have to branch to unlock requirements.
You can, though, skip some content. Stuff like Aurora, Platinum, and such are not enforced. The repeatable beach, pool, etc. Ignoring those won't penalty you in any way, other than you just out missing on game content.
There's no toggle. But you can enable the "Skip Unread Text" option, and just skip it all. And Other Perspective events are not enforced, you can just ignore them all if you want.
I've been asked about translations constantly. Preparing the game to be translated is in my TODO list. But if I tackle this, most (if not all) of the translations will be A.I. made.
If you check your own hints, you'll see that need love points with several girls. You probably need a few more with Hibiki. Choose her on the beach/pool dates to raise some.
Since you're dealing with a mod produced by someone else, I cannot help a lot since I don't know how it works. That said, a bit above the Development Log in this site, you can see where the game stores it's saves. You could try to find where this mod stores it's saves and copy it. This might work or not depending on what the mod does. Good luck.
I'm very sorry for the late reply. When you're trapped in her house, to progress all you need to do is talk to either Fumiko or Satsuki at different times of the day. Talk to Fumiko first, if nothing happens, try Satsuki. If nothing happens, return to your room, spend time there, then try again with both girls. Next update will make it easier to figure out what to do, but for the time being, you know you're doing progress because time advances when you interact with either of them.
Sorry for the late reply. The other perspective memories unlock after watching the other perspective events. You can find those in the menu with the pink eye. As for the missing memory, at night, with Hibiki and Otome.
You need to spend time with Fumiko or Satsuki, during different times of the day.
Talk to Fumiko, if time doesn't advance, talk to Satsuki. If time doesn't advance. Go to your room and skip time there. Then repeat again with both Fumiko and Satsuki.
You know you're doing it correctly if time advances (ex. morning > afternoon).
It's not that complicated. Just spend time with them at different times of the day.
My bad. I thought I answered this. The Town event is under development, and won't be released until it's complete. In that same post of the screenshot, you can read about that.
The saves are stored in: Android\data\com.vendena.haremresidence\files\ You just have to copy the saves folder from one device to another. But, be warned, Android cleans up leftover files when you uninstall an app. Saves are considered leftover files.
Not all achievements are yet obtainable in the game. The grindy ones involve lewdling a lot each of the 21 girls. Picking at least once everyone in the beach event. And completing the pool one, with Suzume too.
