OK, it's probably not number theory, but it is awesome
. Thanks for releasing the source (so I can run it on Linux). I'm on my third game, the first game consisting of me dying before I could properly see what I was doing.

Also you know you're playing a funny game when you make your opponent stronger so he's easier to kill.

Difficult, but worth it.
Great game! Very unique and interesting mechanics. Definitely not for the faint of heart (or mind).

Hydra slaying has a long history.
First explorers who have met hydras were completely unable to do any harm. As they cut hydras' heads,
two new heads always grew in place of each one cut.
Some of them started using clubs instead of swords. However, this was only a temporary solution. A club may
stun a hydra, and make it temporarily less dangerous, but not kill it. When time comes,
it will wake up and attack further. Hydras remained indestructible monsters.
Some mages have been employed to research methods of slaying Hydras. The first thing they have invented
were Runes of Decapitation, which could kill a completely stunned hydra, or permanently destroy some heads of a
non-completely stunned one. Another thing were Runes of Cancellation, which could remove hydra's regenerative
abilities. However, both of these Runes were one-use items and very expensive to create, and thus not practical.
Then, a report came, claiming that heads won't regrow if the sword was put on fire. Apparently all Hydras
in some region were killed using that method. Their meat was found extremely
tasty, their blood good for healing wounds (due to hydras' natural regenerative abilities),
and their scales good for improving armors.
Mages tried this method. Unfortunately, it did not work for them, though. However, they have experimented with
other kinds of magically imbued weapons. It turned out that some enchantments will reduce the number of heads
regrown. Possibly even no heads will regrow. Some hydras could be slayed after these findings, but not all.
It is rumored that some mage long ago created a weapon which could slay any Hydra without regrowing heads, but he got
overconfident and killed, and the secret was lost.
Mages experimented with their magical weapons even further. And they had a new result: weapons which could
cut (or stun) several heads at once. If they cut all heads, the hydra was killed. If not, the Hydra would usually
regrow the same number of heads as if only one head was cut. The mages were happy with that major result.
Of course, some new hydra slaying weapons and magics were created later, but they were nothing compared to the
previous major achievement. The numbers of Hydras kept decreasing, and finally, they disappeared, and were almost
forgotten... And less and less people became acquainted with the hydra slaying techniques, as other people laughed
at them, because their profession was completely useless in these times.
Now you, a young student, have heard about a manifestation of hydras in so called Hydras Nest.
Apparently some brave knights came to kill the Hydras... Brave, but stupid. Even if they equipped themselves with
mighty hydra slaying weapons, they had no knowledge about how to use them correctly. What use is a mighty sword which can
cut ten heads in one swipe, against a Hydra which has only 9 heads? All these knights have been killed.
You are more clever. Since your earliest
years you have had an unnatural ability to count people in an instant, and
your great grandfather has suggested you to pursue the Hydra Slayer career,
and learn the forgotten art of Hydra
Slaying. Now, you will show people that it is not just an useless funny thing.
You take two small magical weapons and some magical items, hoping to rob better
ones off dead bodies of these stupid knights, and head to Hydras Nest.
Of course, not that you are one of these clever guys who are too scared and
weak to be useful in a battle... you could also wield a two handed weapon with
The game counts various statistics about your character.
I think the game is quite challenging, but not enough to require you to use
up all your resources, so after winning once, you can try to win again with
using less items, or taking less wounds, or using different strategies.
The game has two victory conditions (called "winning a battle" and
"winning a war"). After obtaining the first one, you can try the second one
(which should be winnable even without using one of the Potions of Life).
You can try optimizing your play in both games. After winning
the war, you can still go down, although the enemies get tougher and
you gain less and less health, and items are not sufficient, so you will
eventually have to stop.
