A remarkably-atmospheric tech demo, Fractal Sailor lets you explore a eldritch, cave-like fractal structure while refueling far-flung mining outposts. Don't be afraid of crashing into the 'walls' - they part when you approach them.

However, the noises the fractal makes, the never-ending, unnatural shapes, and the sheer darkness make it very tense and atmospheric.

And, of course, there's the giant squid-like thing which will happily toss your ship to who-knows-where should you fail to extinguish your ship's light in time...or just bump into it. It might be deaf, but it doesn't lack a sense of touch.
