clickgame here is a game instruction: Catch all the swimming fish before they leave the fish tank. but they do not leave the tank, they turn around and fly on! what is the game algorithm? fish leave bank or turn around?
Indeed, the fish never leave the aquarium. I've wondered about that when I was reviewing the strings and noticed the same. But I've decided the keep the existing text for now to not break existing translations and audio voices, as this extra part is not really impacting the main description of the activity, that users have to click the fish. Also, as this activity is really just to learn to click on something, I think we don't want to add a time restriction to make it more accessible to everyone. Though we can discuss more about if we really should update the description, in which case we can change it for next feature release.
I've done some animation refactoring on this activity, and now the fish "leave the tank" (they go out of the screen, before coming again), so we can keep the current instruction.
