Coulomb

Coulomb is a game about tiny charges, such as protons and electrons, and how they behave with each other.

Use your mouse to place charges on the screen. You can press space to switch between protons and electrons and backspace to remove charges.

When you think you are ready, press enter and a target electron will spawn on the green square. If your charges can attract and repel the target electron into the purple goal, you pass the level.

Press "L" while hovering over a particle to lock it in place; locked particles will be unable to move whereas unlocked particles can move according to electric forces. Press "B" to turn on the boundary, which will keep all particles onscreen and prevent them from flying off to infinity. Once you are satisfied with your configuration, press enter to toggle the simulation.
