From the README

A puzzle game where gravity is the only tool: place moons, stars and black holes to bend beams of light into telescopes.

What if bending light with gravity were not one gadget among mirrors and prisms, but the whole game? Every mass pulls on every beam that passes it, more strongly the closer the beam comes and the heavier the mass. A single placement therefore moves several beams at once, two masses make a lens, and a black hole can swallow a beam or swing it right round. Lensing is an original puzzle game built on that one idea, with physics that is honest about where it is tuned for play.
