Ok, that might make things a bit simpler. If you only have one unit you might not have to click it to select it, since I assume it will automatically be selected on your round. The best approach will still depend on how you are expected to interact with units on the board, though. Can the units affect the unit of other players in some way, so that they would have to be able to target them? Do you have a PDF of the rules of your game or something? That would be helpful.
