The game concept I have in mind is about isolating a particle from other particles to avoid a great hyper mega explosion. In order to do that you can move the main particle and activate a shield to disable other particles, etc.
The main objective is to avoid the world to be destroyed as long as you can, of course, eventually the world is gonna explode
Here is a small example of what I have in mind:
It is a reaaaaaally simple and basic concept but that is what I think I can do with the time I have. At least I will try to make it fun.
