I tried it on phone, main issue is control, you should pull back on the ball instead of forward to draw a shot, with a level padding to allow space (like a bg wall), also UI like health and others are not very mobile friendly, they need some polish
For cover I recommend a screenshot from in-game with overlayed polished, 3D, shadow drop arranged text, using your image as reference and letting an llm agent open an offscreen game to select a camera position and screenshot it. This will prob take a bit of setup but once done it is fast, and reproducible: make the llm make a script to generate screenshot in-game and overlay text, that way when you update the game you have the ss cover pipeline ready, this can also be done for in game screenshots and generalized into your other games so I think it’s definitely worth doing.
If you are interested I can share some of my game repos where I do it partially or share a concrete generalized solution for this. Supper Guard is a good example of this you can check, the cover, gif, screenshots, even the trailer used a variant of this method. Send me an email if you’re interested I have contact on my page.
