Spectrum Run by Tobias Hagemann $0.99 -> FREE
I found this game a hour ago and I think some of you will probably like it. It's an endless runner similar to Polara where you have to switch colors. This one is super challenging, I haven't reached a score of 200 yet.
In comparison with Polara it has no chance, the graphics are too simple, the controls are hard to master because you have to swipe on the right side of the screen and there is almost no replay value except you're going for a new highscore but it's definitely worth checking out for free.
