I'm currently in development for android.
I tried to use Unity's Play Asset Delivery because the file size would inevitably exceed 150MB.
I built it and started the app, but it's stuck at the Naninovel initialization screen.

Is Naninovel compatible with Play Asset Delivery or is there another way?

Naninovel doesn't limit what you can achieve with Unity, hence it depends on the way Unity support this feature and if it's correctly configured on the Unity side.

I see. I will take a look. Thanks
