![[OLD SEMESTER] 15-104 • Introduction to Computing for Creative Practice](https://courses.ideate.cmu.edu/15-104/f2021/wp-content/uploads/2023/09/stop-banner.png)
I wanted to raise awareness about melting icebergs due to global warming so I created a game where a polar bear must jump on multiple floating icebergs to reach a safer large iceberg. I was inspired by games like frogger and crossy road and wanted to create an interactive easy game that would help users understand global warming better. To play the game user must press the space button to continue and press up to navigate. Land on the iceberg and you will be safe, if you land in the ocean, you will die. Make sure to move up before you drift off into the ocean. Also note that there are some weak icebergs that will break if you are unlucky. If I had more time I would work on creating levels with more iceberg rows and increasing speed of the icebergs, and maybe add more obstacles like a sea lion or natural predators of polar bears.
