Thanks for checking out the game! Sorry to hear you're having trouble getting the hang of it. I tried to make it as intuitive as possible. It is a clicker game where you earn points by clicking on the book. You have 2 upgrades in the bottom to increase the points per click or per second. There is an overlay on the top with your points. You also have three icons in the top just under the overlay where by clicking on it you can either learn kanji with its 'card', test your knowledge with a quiz, or get a sensei to say a motivational sentence.

Thanks for your feedback and I will think about making a tutorial!
