A Continuation of Steam Greenlight
Welcome back to Steam Greenlight showings from 2016 to 2017! The previous trailers I found were part of the Greenlit section, meaning that they have gained a tremendous amount of support from the Steam community. As you can see, people have invented many creative approaches to gameplay.
Once enough people “thumbs up” a game, it becomes Greenlit allowing people to leave their comments or ask the author questions about gameplay. So the next step is for Valve to contact the dev about getting it published, all that technical stuff.
