Interpret it however you like. It doesn't mean your game has to be 10 seconds long. Perhaps there are a series of 10-second dialogues in your game, or you only have 10 seconds to respond to a story arc choice. You can be flexible with it.
I am making a small story game and I've somewhat incorporated the topic in the plot it was not particularly easy but I already had a plot in mind that could be compatible with this sort of stuff. Its gonna be a very short game tho, not 10sec but maybe 20/30minutes if everything in my head goes well. I'm pretty hyped since its my first Game Jam!
