Shouldn’t there be an undo button? – Papa Louie Pals Review

This is a good app, but shouldn’t there be an undo button? That’s the most basic thing. Why’s there no undo button? Even Mario maker, even that had an undo button. And another thing, why do the packs cost money? Can’t we just get them for free?
