Thank you for the reports. I will fix these things as soon as I can.
The statue boomerang thing is now replaced with the regular triangular shaped boomerang thingy. It indeed didn't make a lot of sense.
In the original, the single goriya was the hint.
While this isn't so unexpectable, I wish I thought more on many of the rest of the triggers. Not necessarily having the same basic triggers like in 2001-2004's quests, just at least teach the player what is what specifically here and actually make it learnable, instead of one-time-use triggers and many exceptions.
Really, if I made BB in 2014 and onwards, I would have had this like this: a Goriya keeps throwing a boomerang at the statue and when the player throws it, the statue triggers and the Goriya is shown somewhat angry/frustrated that the player could do it for first.
My original idea was to have the Goriyas be an actual race, like Zoras or Gorons, not to have them only as monsters, exactly how I did with Subrosians from BBII onwards. But without this idea, the one trying to boomerang the statue better could have been some adventurer, especially a Zora, to follow with the plot of the area/dungeon.
By all means, I love what T_K did with BB.
