“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?”

“A truly non-Euclidean tactical puzzle/roguelike!”
