To continue with tradition, I made a game for this Ludum Dare named Leave me Alone!! (sadly, it seems like there are 3 or more games named that way).
I had little time to spend making the game so I targeted a simple game with almost no graphics nor sounds but fun.
The story behind the game is, you have to isolate a particle from other particles to keep the world safe, if they make contact then the world explodes in a mega hyper super duper explosion (use your imagination).
Here is a screenshot:
And here is a gameplay video.
