"We are ending sales through Impulse due to GameStop's long, negative behavior toward the PC platform and independent games," the developer's statement reads. "We would never have signed onto distribution through GameStop, and being forced into this situation has only made it worse for us." Blind Mind notes that its history with Impulse has been positive to date, and, "We supported Brad Wardell's direction of Impulse." Wardell's absence "ruins our faith in the service's future."
The developer is working to ensure that updates and patches will continue to be delivered through Impulse to anyone who bought Star Ruler from the service. Barring that, it will release an automatic updater of its own.
