Yes, on mobile it was a little more playable/easy, but still rough for me. I'm not much of a gamer. Perhaps you can have an -easy-easy- mode that will auto ping at a configurable interval. You still have a few days, that might be something to add.
memory retention is I suppose an external mechanic of the game - remembering the layout. having a continuous ping would break this I feel. although, if there is a call for it I will definitely consider implementing
