The position and timing of walking are important concepts in the game, and you need to explore them in the game, as long as you use them flexibly, you can play freely and gallop on the battlefield. This is a personal development of an independent game, out of the love of action games, spent years to complete this work, I hope you like! At the same time because of the limited time and manpower so the picture can not do too exquisite, but does not affect the game experience. Welcome to leave your suggestions and comments! I will continue to improve, thank you!
