Purring Engine by Team Pawsitive

Purring_Engine is a simple but effective custom 2D game engine, developed using C++ with OpenGL for rendering. The engine includes:

• A level editor
• Component-based architecture
• Sprite batching and instancing
• Custom algorithms for physics and collision detection

This engine was designed to support the development of March of the Meows, a 2D turn-based strategy game with a real-time twist. More details about our game can be found below.
