Spectra is a fiendishly difficult turn-based puzzler where every move you make has consequence. Carefully balance your energy levels as you negotiate a pulsating neon maze-scape and avoid geometric enemy patterns to get to the exit square. The basic concept is simple, each move you make advances the game world by one turn. You are either getting more powerful by moving onto the grey squares or loosing power. Gain 5 energy and you will raise a color level. Raising a color level enables you to enter locked squares and overcome enemies that have an equal or lower color level than you.
