This is a project on coral bleaching. Click the green flag to start. Click space after the intro, (When you see stars), to see more information on coral bleaching. When you get to a backdrop with coral and sliders, move the sliders to simulate coral bleaching, and what effects it the most. WARNING! The light level and amount of nutrient sliders aren't realistic. I didn't have time to make any changes to those. I might fix this later. Make sure to hit the space key hard enough, or else it will stop working. I do not know why. Don't hold it though. Just hit it firmly. If you see a plain gray screen at any point besides the intro, then stop and start the project again. This should fix it. By the way, there's no pen.

My science teacher told me to do a project on an environmental issue. This is my project. @LAB-Seal for the Parrotfish, (The fish eating the coral, well, really the algae.), and the flying fish, (The fish that appears at the top of the screen sometimes). All code by me. Coral sprite by me. Yellow fish sprite from Scratch.
