I've been learning a few coding languages off of Codeacademy recently. One of my first major projects I've chosen to do is a text-based adventure RPG game. I'm too lazy right now to go into details about it, so try it yourself!
To play you must click the "Run" button in the top-right corner of the white box (around the top-middle of your screen). Then, read the text that appears in the black box on the right and answer the questions in the box. So far there are 6 different endings. :D
