Here's a fairly decent YouTube video presentation, but this guy seems like a rah-rah booster. He does a good job explaining how the mechanism works and has prepared some good animations.

This big problem that I see are the sliding valve seals. Rotating sleeve seals have always been the Achilles heel of many designs compared to poppet valves in a conventional ICE engine.

Liquid cooling would appear to be a serious challenge, too.

When I first saw this design I thought "the rotating mass will act as a flywheel eliminating the external flywheel." The narrator of this video makes that point.

“When I first saw this design I thought “the rotating mass will act as a flywheel eliminating the external flywheel.””

Is balance / vibration going to be an issue with the reciprocating piston or is it naturally damped out somehow?
