Doodle Jump was one of my favorite games I used to play on my phone, and I wanted to make a multiplayer version! I learned how to use the arrow keys and the "awsd" keys to make the players move at the same time. I made different types of platforms. Some are stationary, some move side to side, and some even disappear after a character has touched it once. I also learned how to make it look like the characters are moving by scrolling the screen.
