My project changed a lot from what I originally intended. At first I wanted a more traditional, Mario-like 8 bit game. However, while I was working on my project I started watching the show Supergirl and fell in love with it, so I wanted to make a game based off of her. Instead of running around and jumping, the player character (Supergirl) flies through the air to save Lois Lane, all while trying to avoid obstacles in her way.
This was a lot of fun to make, and hopefully in the future I can make something more complex!
