Built by educators, PixelPAD is a web-based 2D game engine designed for classroom and personal projects. It uses Python but doesn't support the entire language yet. It is free to sign up and use but there's also a subscription available to gain access to educational material as well as a la carte options for individual courses.
The engine currently exports to the Web but based on its disabled options, mobile and current-gen console export could be around the corner. I'm curious to see how this engine gets developed!
