For my teacher: I'm not sure if you've used Scratch before, so while this may be redundant, I'll say it anyway. First, you would need to click the green flag around the left side of the screen, underneath the profile picture (Or the one on the project itself, forgot about that one). This starts the project. (You can also go Fullscreen if you'd like with the four arrows pointing away from it's center around the upper center of the screen.) Afterward, you would hover over (it should get darker) and select a box. This opens up a question. The buttons at the bottom work the same way. After answering, they will change color depending on their accuracy. Your Karma (top left) will change accordingly. You can click almost anywhere to progress (not the flag or stop, though, they'd make you restart). You will continue this until all the questions have been answered, after which you will see your score. If menus overlap (I think I fixed it), it is likely a visual bug, and shouldn't interfere with the game.
This was the result of a project meant for History. There are a lot of things that could be better and that I wanted to add, but I ran out of time. Perhaps I could make an updated version in the future. (It'd have to be a separate project, in case someone wanted to refer back to this one for some reason.)
