Hy
I think
Something isn't right
I reach all the fragments of the key 
that in little box  was deen realy cruel one)
BUT
After all this, I can't open the treasure
that say we need all 3 pieces and repeat this
maybe I figured something wrong?

Edit: oh i just restart game? and that hekp me figure out, key(not fragment) from lil box is for desk hmmm...
Maybe all good this just me so silly...3
