Yes this is made in the same engine as Drift Shell.
If my games make enough profit for me to go full-time indie dev I'd like to make the engine public to use. For now it's a private personal tool of mine. There's alot of work that needs to be done to make the engine practical for others to use other than me. Plus making built in modding support for games made in the engine.
It's encouraging to see so many requests for modding and dev tool access tho. My 'Seafoam" engine is a part of my expression in response to this Era of the game industry. And I would like to share that with others eventually.
