Theme interpretation
Color schemes: Blue is good whereas red is evil. An intergalactic battle is taking place in the skies between these two powers. The world is also slowly being overtaken by the evil of red and that's why triangles/darts have red outlines and sections between rectangles are also red. If you hit any of these or the infected red cannon or evil UFO gets you, you'll die (other than by crashing into things). When you die, you'll turn red or dissipate into the atmosphere in a fiery explosion of red as well. Hopefully, you'll survive through these troubles and avoid death in the midst of this intergalactic struggle.
