Independent developer Jay Tholen's point-and-click clown adventure Dropsy has nearly concluded its successful Kickstarter campaign, and will be hitting PC, Mac, and Linux in October 2014.
Dropsy's gimmick is that the game is completely non-linear, allowing players to choose what parts of the adventure to resolve in any order they like.
The game was originally a "Choose Your Adventure Game" back in 2008, but evolved into a full-sized adventure game. The game has raised $20K; the original Kickstarter goal was $14K. There are still three days left as of the writing of this article.
