Like Compass, this one was abandoned back in 2013, and picked up again in 2017 when I remembered how much fun twine is. It's the closest I've come to making an actual game, but it's more like a maze with aliens.
The Invader is set on the marine lake in West Kirby, my hometown (see below). It's a faithful recreation of walking there at night and listening to 'Black Rose Green Sun' from the Homestuck soundtrack, which I strongly recommend you put on in the background for an optimal reading experience.
Another important influence was 'The Sea Raiders,' a short story by H. G. Wells which you can read here. The Invader owes a lot (including its title) to my slight misrememberings of this fine piece of pseudo-journalism.
