Are there any geometric sans-serifs that can feel playful and less rigid than typical examples, similar to Comic Sans' informality?

While geometric sans-serifs are often perceived as rigid, some have softer qualities. 'Montserrat' or 'Lato' (though humanist, has geometric influences) can feel quite friendly. Look for those with slightly rounded elements or more open counters. 'Varela Round' is a purely geometric sans-serif that explicitly features rounded terminals, offering a playful yet clean aesthetic.
