With Rex Engine, you can get a 2D sidescroller up and running in minutes. It provides easy hooks to swap in your own art, animations, and music, and gives you endless customization options to create and customize your very own killer sidescroller.
Jam-Packed with Mechanics
Rex Engine gives you access to a huge variety of character mechanics and abilities. You can make characters that move, jump, climb, use attacks, and much more.
