Can you make it compatible with Android 15 snapdragon685 octa-core?
If you tried the demo* and it's not working, there's not much I can do unfortunately. Compatibility is provided by the game engine the game is built on (Godot), which I have no control over.
Is there anything specific that happens when you try to run the game?
*I'm saying the demo because the demo has been optimized in terms of memory consumption, and a bug affecting performance that has been there from the very beginning has been fixed. This is the case with the demo (based on v0.9.8), but not yet the free full version (based on v0.9.2). The next free release will address this in the future.
Thanks. Re: textures - I can't remove textures in the arenas - they're pretty much integrated, and it would create a lot of complexity when it comes to modded arenas and such. But I strongly doubt textures are what cause framerate drops. Following 0.9.8 and the performance fix I've had people with very old devices getting a pretty big performance boost, in some cases up to 100% or even more.
One thing to try: select Low or Medium resolution in Options, and go for FSR ultra quality or quality.
