I've been working on a spiritual successor to Jumping Flash Based in Space (1930's version of space with clouds, air and gravity) based loosely on Flash Gordon(1934) and Adventures in Slumberland(1911). Its built with Unreal Engine 4. I should have a demo ready in the next day or two, let me know if your interested, in trying it out.
Keep In mind its a children's game.
