Hey, sorry to hear that the game isn't performing too well on your device. I've been making note of all the Android-related issues so far, but until I can replicate these issues on my end, I'm afraid I don't have the knowledge necessary to further optimize this game or blindly fix any underlying causes.
All I can really say is that this game has been tested to run smoothly on Android devices manufactured since 2022. Older, lower-end devices will probably struggle to handle the game's physics stress, but unfortunately I've already exhausted most of the common optimization tricks by the book, and I've been rather limited in finding any new ones right now. Sorry for the inconvenience.
