Mini-Golf

Thanks to MIT App Inventor.
The ball will bounce off of the rectangular obstacle and the sides of the course. For each fling of the ball, the stroke count goes up by one. The total score is the number of strokes it takes to complete the entire course.

This game entails:

Using the Sprite component and the TouchUp, TouchDown, and Flung events
Using a Clock component
Dynamic Positioning of sprites on a canvas, based on the size of the screen
Sprite Collisions
