fix: tech quiz from not working

fixes #21

@vrindavan you forgot to include 5 lines of code in the game.js of the Tech Quiz and this issue happend lol. But, I can't blame you cause you had to edit so many JS files, I'm making a issue to format the files properly, so it doesn't become difficult for me or the contributors of this project.
