Prowl is an open-source, MIT-licensed game engine developed in pure C# in .NET 8, (which surprisingly has no runtime fees believe it or not! 😮). It aims to provide a seamless transition for developers familiar with Unity by maintaining a similar API while also following KISS and staying as small and customizable as possible. The goal is a viable open-source Unity alternative, ideally, Unity projects can port over with as little resistance as possible.
NOTE: Please keep in mind that Prowl is incredibly new and unstable, and it is not yet Game Ready, however, we are hopeful that Prowl will be stable and ready for simple games by the end of this year. Also all development is currently on the Development branch, Main branch is reasonably far behind as of writing this, We plan to merge back in soon.

Whether you're a seasoned developer or just getting started, your code contributions are invaluable. We have a list of open issues that you can tackle, or feel free to propose your own improvements.
Encountered a bug? We want to know! Submit detailed bug reports on our issue tracker to help us squash those pesky bugs.
Have a fantastic idea for a new feature? Share it with us! Open a feature request and let's discuss how we can make Prowl even better.
Not a developer? No problem! You can still contribute by spreading the word. Share your experiences with Prowl on social media, blogs, or forums. Let the world know about the exciting things happening here.
We're not just asking for contributors; we're asking for partners in this journey. Every small contribution is a step toward realizing Prowl.
All contributors will be acknowledged in our Acknowledgments section.
Thank you for considering contributing to Prowl. Together, let's build something amazing!
- Hat tip to the creators of Raylib, While we are no longer based upon it, it has shaved off hours of development time getting the engine to a usable state.
- Some ideas/code have been taken from the amazing 2D Engine Duality.
