Arachne

Long ago, it is said, Arachne the Spinner was cursed by the goddess Athena, mutated into a spider as punishment for her arrogance. Arachne now dwells far below the earth in the caverns of the underworld, ruling over a kingdom of monsters and sending out her children to spy on the world above. Bitten by one such spider, you find yourself succumbing to the same curse, slowly transforming into a terrifying half-spider monstrosity.

Cast out from your village, you have but one hope to undo what has been done; to travel deep into Arachne's domain and slay her before the transformation is complete. No mere human could possibly hope to navigate the web-filled caverns, but your new form has granted you powers that mean you may just stand a chance...

Arachne is a roguelike created in seven days for the 7DRL Challenge 2016, the obligatory twist on the standard formula being that rather than a standard grid, the game takes place on a dynamically deforming spiderweb that you can build and destroy while you play.
