After a successful Kickstarter and two-and-a-half years of development, Haiku the Robot has been released on Steam. Fans of Hollow Knight would do well to keep an eye on the cute but challenging Metroidvania platformer where the titular robot hero, Haiku, navigates the virus-corrupted world of Arcadia. The most impressive thing about the new indie title, however, is that it was the work of a single developer: Jordan Morris.
