TimothyEarley/scifiPlatformer ? reverse-engineered prompt

Build me a simple sci fi platformer game in Java.

I want a playable side scrolling game with platforms, a character that can move and jump, and some cool lighting effects to give it a futuristic feel. It does not need to be huge, but it should feel like a real game and be fun to test. Please make sure the game starts cleanly, runs smoothly, and includes basic gameplay like jumping across gaps, landing on platforms, and reaching a simple goal or end point.

Use the existing project structure if it helps, and keep the code easy to understand so I can tweak it later. If you need to look up current Java game development details or best practices, go ahead and check online. Also include a basic way to run it from the project without extra hassle.
