Good idea, i think that it needs to make the cross less distance in the first ones, and maybe a button to command "follow" and "wait", a zoom out when building great bridges, put a little force on the top of the stick when released to the bridge always fall forward, i think that way it will be good if you update after the time of votes when it will be allowed.
to update the game
You put sensors on the followers to jump when needs, good work.
