What is 2.5 d?

2.5D refers to a type of graphical perspective where two-dimensional objects are given the appearance of being three-dimensional. It involves creating layers of flat images to simulate depth and perspective, while still maintaining a two-dimensional layout. This technique is often used in video games, animation, and other digital media to create a sense of depth and immersion without the complexities of true 3D modeling. Some examples of 2.5D games include classics like Sonic the Hedgehog and Super Mario Bros, as well as newer titles like Limbo and Ori and the Blind Forest.
