I made a local multiplayer game for 12 players. Normally this is hard to show within search results, and in any case takes a whole lot of keywords or even filler text. So it was nice to see that the player count is an information you can actually enter as part of the description here. It even has a nice slider.
But unless I overlooked it, there is no option to actually search for that information. Since users can already select things such as one-button-game and local multiplayer, and since the information is already there, it would be great if they also got a slider or field to select the number of players they need.
