SimpleHMEngine by: Zakaria Djebbes

A small, hobby 2D game engine built on SFML.Net: game loop, scene/component tree, input binding, camera, simple collision, an immediate-mode drawing helper, and a lightweight UI toolkit. Great for prototypes, game jams and learning — not a production engine.

ZGeometry by: Zakaria Djebbes

A small, generic 2D geometry library for .NET: a numeric Vector2D<T> and primitives (circle, rectangle, triangle, line, point) with fluent Overlaps/Contains/Intersects queries, generic over any INumber<T>. A hobby library, great for games, prototypes and learning.
