This document discusses the development of a 2D platform game for children up to 5 years old that incorporates a physics engine. The game aims to teach basic concepts of physics like friction and collisions through play, while also imparting early education on alphabets. It was created using GameSalad and an integrated 2D physics engine to govern environmental objects and player movement. The game went through various testing stages including functionality, compatibility, beta and regression testing to ensure quality.
