Kunundrum creator Hope This Works Games has released Polara, a polarity-switching autoscrolling platformer available for iOS and Android devices.

Polara blends the polarity mechanics of Treasure's famed shoot-'em-up Ikaruga with the structure of a free-running platformer. Players must quickly change polarity at specific points within each level in order to use like-colored ramps and speed boosts while avoiding hazards of the opposing polarity. The game includes 50 story-based levels, along with a handful of unlockable endless challenges.

Polara is priced at 99 cents.
