Has anybody upgraded yet? can it be upgraded multiple times?
I would guess so. The first upgrade is one extra honey per 3 hours - that's worth 24 coins.
I have a problem with getting hammers so can't upgrade.
My ID is ciarjen if you would like to add me
I play Dragon story (island name is Yniop), Castle Story (kingdom name is Langley) and Farm Story 2 (farm name is Batty's Farm).
