I'm playing on fairly powerful Android 13 tablet. First I tried the native Android version. It was fine except that motion was rather jerky, making it almost impossible in a battle to get the pointer to stop in the green region. So then I tried the Windows version using Joiplay. I no longer had this problem, so the game was playable. However when the area one was looking at panned to left or right it produced very thin black vertical lines across the picture, which was rather unsightly but didn't prevent me from playing the game.
