The plot of the game tells the story of a Despereaux mouse, whose attributes are extremely large ears. This mouse lives with his whole family in a beautiful, stately castle. It is here that she faces numerous adversities that face her love and, at the same time, cost her a luxurious life. The main character of the game, from the very birth, has always been unique in some ways. Who would have guessed that a tiny two-inch mouse might have books and music among its hobbies. Who could have guessed that the same mouse would fall in love with Princess Pei and when she was kidnapped, she embarks on a dangerous and adventurous journey to save her. Both animal and human antagonists wait for the mouse on this journey through the castle. Fortunately, our main character is fast, agile, flexible and quite small, thanks to which he can escape even the worst of problems and continue on his journey to love. Fortunately, on the mouse's path to success, there are also positive, friendly people. In the game, we visit various nooks and crannies of the castle, we can visit the kitchen and colorful, rich chambers, as well as the dark underground of the kingdom. There will be bees, spiders and rats on our way, and we will have to demonstrate great acrobatic skills to get to the cupboard.
