This is ChargeBall, a game by St:a Snackers that simply imitates
the laws of Nature.
The thing you do is simple. By clicking your mouse somewhere on window, you
can steer that smiling little point-particle round the screen, (which basically
is YOU, in a nutshell). The thing you wanna do is to make the other balls enter
the goal. Isn't that simple!
The balls indexed with a plus
sign are attracted to you, and respectively
the negative
are repulsed. You will have to push the negative into the goal,
and pull the positive. That may be hard in the beginning, but after 30 days, you
may have got the hang of it.
