This is a screenshot of a game I made using blackbird. It is unfinished and has many bugs, and there is still a lot I want to add to it. You move around the small square, and by touching the yellow circle, you damage the big square in the middle. Currently, the enemy cannot damage you unless you accidentally touch it. In the future, I am going to program attacks for it, as well as upgrades to buy with the gold you get by defeating it. Upon deafeating it, it also gains more health and does increased damage.
