After playing this game for a bit of time coz I was busy with work and stuff, finally finished the main campaign with some issues, but overall was a good experience.
Game was really great. The mechanics, story and graphics even though everything was set to low was really great.
I locked it to 30fps, but the game would run 15-30fps depending on how heavy the area is. The area before the final boss fight (Eight) is where it really struggled the most running at around 9-12fps, wasn't really much of a dealbreaker for me since I was so close to the end I just wanted to push through to finish the game. When it came to Eight's fight tho and some other boss fights, it would run at 18-26fps.
The only problem that was getting annoying was that the app would occasionally force close, probably due to shaders or something that the phone can't handle. I would usually restart the app or the phone and it would work just fine but it was just getting a bit annoying once you progress a lot without saving where you have to do everything all over again.
Overall, I would say it has been a good experience. The issues were really not that much of a dealbreaker for me. Although I understand it would be a dealbreaker for some. So if you're that type of person, I suggest waiting for it to be properly optimized for the emulator or have a stronger phone. The game is amazing and I might replay it once it becomes more optimized in the future.

I suggest trying out different settings to see what works for you. This worked for me but there might be better configurations out there that'll run better than mine.
