If you check the pet games, few players are using the cannon. Why? There is only one test shot and three regular shots. Even worse, once a players gets a bulls eye , the win and speed changes without allowing for any test shots. This results in much fewer wins than with the dance game or maze game. Accordingly, you should provide more test shots for the cannon to allow players to zero in on the bulls eye . At least two test shots should be implements after any wind speed or directional change. Also, each hit should give more points.
I almost always achieve the max 4 points. I use it less than the Dance game because dancing is faster. Please don't make any changes that will slow the cannon down!
