If you are on mobile then there may not be anything we can do since pretty much all the graphic options are disabled. If you are on PC or Linux, you can enable the Low Detail mode in the options to make the game run better.
I play on my phone but it's fine. Thank you for your advice. Will you have an update to improve the graphics on your phone?
It's not currently planned as we did what we could to improve the performance there but if we find a new solution we'll work to implement it ;)
Thank you.
