The energy creature named Stix is trapped in a cosmic storm and can now be used as an energy source for mankind. With the help of a field synthesizer you need to take away space from the Stix by creating force fields inside the area in which it moves, the hypersquare. But there are four perils that make life difficult for you. If you have not finished a force field and Stix touches a part of it, your field synthesizer will explode. Also, the "quark" and the "anti-quark" are walking the inner border of the energy fields and they destroy the field synthesizer when they touch it. Due to a fault in design (admitted to by the manufacturer) the energy in the synthesizer will build up and make it explode if it stops for too long while building up an energy field. And finally, the synthesizer has only a limited amount of fuel.
