The game world is interesting because you can get into any point, go deep into the dungeon, go up into space, so why not get into the matter itself and see what is happening there at the level of atoms. The game Particle Pandemonium will allow you to do this and you can even help the electron and its companion positron go through a lot of different levels, find keys and open all the doors that are on the border of the levels. Sometimes the electron cannot reach the key and then his little friend will come to the rescue. Switch actions to it with the E key and help the positron get the key in Particle Pandemonium.
