Plasma Sky is 80 levels of vector-like, heterogeneous, fast, intense, classic shmups (shoot them up) action. You get a lot of variety and quality gameplay for a very small price. No filler here whatsoever. Developer is a single-man venture, and deserves as much praise and profit as possible. The App Store could do with more honest-to-goodness titles likes this.
