So write it. Make a deck of cards to use instead of the phone. Or a CYOA booklet. The phone part is fun but it doesn’t sound super necessary. Get the game part right is the important thing. But also you could mock this up pretty easily, just rip the guts out of an old phone and replace it with a raspberry pi. Use a keypad phone instead of rotary, it’ll make your life way easier.
