I have a problem: whenever I get to Leif, the game lags and crashes. I'm playing on Android with a Redmi A5, and it doesn't matter if I start a new game; the same thing always happens. Also, I see in this update that they've removed the cutscenes where Cervius could animate an ally so they could take another turn. I don't know why, but believe me, I really liked the game before this update. I played it a lot, but the removal of the animations when I get to Leif is really annoying. I don't know if I need a new phone for it to run properly because I don't have a computer, just an Android phone.
Based on the specs I see of your phone, I'm pretty sure it should be enough to run the game. Just to make sure, go into the options and make sure you're using the low res settings (though I believe that should be default on phones).
Looking at your comment I also see that you played the game a very long time ago, if you're reusing an old save, I strongly recommend starting a fresh game if your save is older than august 2025 or you're going to run into a lot of bugs.
As for the animations with Cervius, those were not removed from the game and instead moved to the pleasure room where they can be unlocked to then be used in the Stage Performance minigame. We made that change so we could have more freedom with the animations and also make it so it's faster to do the battles.
