Playful UI only works before people need certainty

i keep noticing that a lot of playful ui choices are basically fine in demos and kind of annoying in actual use. a button with a cute label or a vague icon can feel clever, but once i’m trying to get something done i’m suddenly way less amused.

maybe i’m just getting old, but i think clarity earns trust faster than personality does. where do you all draw the line between charming ambiguity and just making people guess?
