This is a tag game between a cat and a prairie dog. Press the green flag and then space bar (and hold it a bit) to start. The cat will run in the direction of the Mouse's pointer. Notice that the cat runs slower if the mouse pointer is too close to the cat's head. The cat only gets the prairie dog if their heads are close, which allows the prairie dog to escape even if they touch each other. Each round has 3 plays. After each round, the prairie dog runs a bit faster. The game ends after round 4. You have better chances to catch the prairie dog if you approach it with acute angles.
Got the 8 cat and 3 prairie dog running cycles from the internet (pngs were made with Photoshop and shadows added in powerpoint). Same for the songs' notes. This game was created to show simple animation and the use of trigonometry functions to my middle schooler. If you are interested, take a look at the code, specially the "hole" and "prairie dog sprites". The escape function is not perfected so there are some glitches (like the prairie dog dancing around the destination hole) you can fix. No animals are supposed to be harmed in this game. This is just a tag play.
