The Last Door
This is a free, crowd-funded point & click adventure with a spooky theme and a reduced visual style. The first three chapters are free, but to continue beyond you need to be a supporter. 5 parts have been programmed so far.
I’ve finished the first 2 chapters and I guess I’ll donate because “The Last Door” has a gripping story. It relies heavily on the eerie atmosphere created by its sound track and the makers of this game suggest headphones and a dark environment.
Give it a try! (free account necessary)
But don’t watch the trailer on their website. It contains spoilers.
