Free horror game Fractal Sailor is about flying an airship through infinite godflesh while eluding a monster

If ever there were a game not to play on a Monday when you've had minimal sleep and basically want to crawl under the table and eat three-day-old pizza, that game - or rather, free "tech demo" - is Fractal Sailor. The work of Struct9 founder Matej Vanco, it hands you a distressingly unwieldy and roofless hovership and cuts you adrift in a vast ocean of malevolent mathematics.

Your task is to visit and gather energy from a series of bulging, biomechanical power stations while avoiding the attentions of... something. Said something is deaf, meaning it won't hear the frantic beeping of your proximity indicator, but it isn't blind, so be sure to switch off that bowlight once the proximity indicator starts a-singing. Other telltale signs that the creature is near include a hideous dirge, like the sound of a billion buzzsaws carving a hole into a neighbouring reality. Hmm, I wonder if it's a cousin of the Maw?

The obvious comparison is the amazing Yedoma Globula, but Fractal Sailor is much more focussed. It's Slender: The Eight Pages by way of Iron Lung - an awkward scramble to meddle with every last interactive fixture while maintaining a low profile.

Your ship can travel both horizontally and vertically, and it's easy to get lost in the ebb and flow of Stygian geometry. You've got a radar pulse that highlights stations (and your monstrous pursuer) as holograms, but gauging the range and the exact tangibility of intervening objects is tricky. I also found docking with stations to siphon energy a struggle: you've got to line up your ship with the correct bit. You can disengage with the steering controls to trot around your vessel, but as far as I'm aware, it's not possible to fall off. I fell out of my
