Dragonscapes takes up an insane quantity of storage – is there any strategy to cut back it?

Hey everybody! My mother has been taking part in Dragonscapes for some time and lately observed it's taking on far more area than anticipated on her Android telephone. It's MiUI 14 (World), Android 11, Redmi Word 10 Professional. Proper now it’s utilizing greater than 28 GB (see screenshot), which appears actually excessive for an off-the-cuff sport.(I’m not even certain what the sport is about)

Tried clearing cache, however the app nonetheless utilizing a ton of storage. Is there a hidden setting or choice to scale back the dimensions, or is it simply poorly optimized?

I couldn't discover any subreddit for the sport itself, so I assumed this is able to be the perfect place to ask. Thanks upfront for any ideas or insights!
