I’m currently in the middle of developing a remake of Quantum League using LibGDX. It’s like an FPS, but game mechanics involve an “echo” re-playing your previous movees, so if you can kill an echo that killed your earlier echo, your earlier will still be effective. (I hope that makes sense!?)
The graphics aren’t very good I’m afraid, but the gameplay is getting there.
