Oh, I didn't know there was assist systems for those things you described. Sorry for the trouble this game caused you. For what it's worth I expect it to be once ever and not come back. They seem to come up with different ideas each year. Even this minigame, when unlocking it for repeats, doesn't seem to have letters and numbers any more. I'm trying it from the toy box at home and now it seems to be only searching for a key through the maze and then using the key.
