As such it could be fun, but it is a hard balance to add to this game considering the amount of Clicks needed to play the base game.
Fix/change AID in some way, reducing the every day need for it (or somthing) and I´m as such in for funnier things to click on.
But such joyful interactivity as to steer a boat in Venedig added to the amount of players world wide on HTML5 / Flash system...
I think Inno is not really equipped to implement that (I could be wrong) – it will be heard justify if it is not also compulsury or create an extra benefit/chance – which would bring the game much closer to arcade style.

It really depends on how it is done and if meaningful balance can be made, making it fun enough anf giving enough chance for people wanting to play, while the game still can be played without it as well [In Event].
