The discovery of non-Euclidean geometry has changed how we perceive the world... but geometry goes even more exotic than that! Games of various genres designed for Thurston and space-time geometries.

You face a 9-headed hydra. Your sword cuts 5 heads in each swipe (never less), which kills a 5-headed hydra, but a larger one will regrow 2 heads after each swipe. Your scythe cuts exactly 7, but 10 grow back if the hydra lives. Can you kill the hydra? Or better to explore to find more arms first?

Time moves when you move in a truly non-Euclidean world
