It’s no revelation that retro/vintage style is popular these days. Cars, clothes even computer games.
Geometry Wars, Gravity Crash, Pew-Pew and many more share a certain pattern, simple vector graphics and arcade style.
Orbital is a peculiar game. If Missile Command, Arcanoid and Puzzle Bobble shared a night of passion – then their offspring could be Orbital
I highly recommend it for anyone wanting to “waste” some time.
