Read a fictional story about Charlie and Natalie as they are whisked away to the future to try to stop the invention of time travel itself! Every couple of chapters you get to play as Charlie and Natalie in a game where you help them progress through the story. Unfortunately, each game is broken and needs your help to fix it.
The next few pages after a game will guide you on ways you can fix the game, but you are given complete freedom to fix it however you want. Each task you complete earns you a sticker that helps put the time machine back together. If you complete enough tasks and fix the time machine, then you unlock the final chapter to see how the story ends.
It's a sci-fi story but also a game design tutorial that's great for kids or for people just getting into game design.
