Just a minor thing - but since this game can be played without keyboard (excluding the chat) how about adding another button on the screen while fishing?
Its action would be the equivalent of pressing spacebar on keyboard.
You could title it "Set the hook" since it seems to be the way you call pulling the fishing rod when fish starts to bite. Simple "Pull" would be my choice.
I still havent tried other professions but if they also use only spacebar for actions - you could apply this there too.
Like i said - minor thing but devil (as always) is in the details.
Nice game btw
