I was pretty concerned about this too, but one reason for optimism is they have a very experienced professional game developer on their team, Brandon Reinhart:
Brandon has been a professional game developer since 1998, starting his career at Epic Games with engineering and design on Unreal Tournament and Unreal Engine 1.0. More recently, Brandon spent 12 years at Valve wearing (and inventing) hats. Many, many hats… Brandon has spent considerable amounts of time in development and leadership on Team Fortress 2 and Dota 2 where he wrote mountains of code and pioneered modern approaches to game development. Also an advisor for the Makers Fund family of companies, Brandon offers his expertise to game startups at all stages of growth.
