Young Souls. I'm pretty forgiving when it comes to couch co-op games if we find one we can both enjoy.
And this one was good, but it was basically unplayable on the Switch (or, at least, constantly crashed mine). Finally got to the very end (where there's no saving from the start of the end cutscene until the finale) and it crashed before the final battle. Restarted, got through several minutes of cutscenes, got a little farther but crashed again, this time in the final battle. Tried one more time and it crashed again in a different spot. Promptly deleted the game.
So I guess we'll never finish that one.
It locked my ID. I successfully unlocked it, but then it asked for my security questions to log in, and I must've forgotten those. I tried to reset them, but got a weird error ("not enough info to reset"). Apple Support was unhelpful, just told me to try again the next day (yesterday), which didn't work, and otherwise said I'd just have to create a new Apple ID.
