It hasn't been held since 2015. If it is a success, I can imagine it will return again already next year.
Perhaps it will pull some parser games from IFComp. I am sure all games will get reviews.
And as it is held on itch.io, your game gets ratings in several (currently unknown) categories, though only the overall category decides how the game is ranked. Still, it would be interesting to get feedback in all those categories such as puzzles, parser, atmosphere etc.
