Would it be possible to extend the search time to 10 minutes?
With over 40 collectibles to find, I decided to use the Fairy Fire, only to have the time run out before I had located them all. Unfortunately, a couple of them were amongst paused buildings, and my older eyes were unable to locate them amongst the other blue moving objects.
I realise that this is not a problem for most players, but I suspect that there are other older players with fading eyesight who may have trouble finding objects.
