Play the game... explore every nook and cranny, then you'll know if you've pressed the right thing. It ends with saying NOTHING, and if you want me to make a second version then say so in the comments. I would really like if you gave me any advise, and please don't edit the programming, this may not have taken long, but it still took a lot of work animating the signs falling.
This project is partially unfinished. If you would like me to finish it I will gladly do so. For now though, I will be working on other projects.
