Sammie Kim – Final Project – 12

For this project, I wanted to create a recycling game that educates all age levels upon proper recycling, which is one of the basic ways that we can all contribute to protect our environment. Through the process, I learned a lot, especially how there are a lot of trash items that are not recyclable—this emphasized the importance of reusing items and reducing waste in general. The user can simply explore the environment, drag any waste item and drop it in any of the waste bins below. If the waste is thrown in the wrong bin, information will automatically show up on the top to guide the user, while also giving extra tips for reducing such trash.
