FluffyBrudy/pygame-examples ? reverse-engineered prompt

Build me a small Python game examples project using Pygame that shows off a couple of simple demos.

I want one demo that does a basic 2D raycasting scene, like a simple first person maze viewer with moving around and walls getting drawn from the player’s point of view. I also want a second demo that feels like a Sunnyland style platformer, with a little character that can run and jump around a side scrolling level.

Keep it clean and easy to run, with separate example folders if that makes sense, and make sure each demo has its own entry point so I can launch them separately. Use simple placeholder art if needed, but make the scenes feel polished enough to demonstrate the idea. Add clear instructions in the README for how to install what’s needed and how to start each example. If you need to check current Pygame setup details, look up the latest docs online.
