Ballocks mod for Half-Life 2

Idea:
Ballocks is a total conversion originally inspired by the 1986 movie "Critters".
You play the role of a Ballock, a small hairy creature with a craving for female blood. The Ballocks race is evolved from the men into selfreproducing animals that lives in dark forrests and has no need for women. Meanwhile the women of the planet has hardly evolved, but they have grown fond of pink laser weapons, and they are indeed dangerous.
Your goal is to free your ancestor who is kept alive by the females in order to serve as a sperm donor.

Gameplay:
Key features includes: eating corpses, shooting arrows, high paced movement, blood..and lots of it.

You have two modes of moving about, standing/walking and rolling/bouncing.
In ball mode you can bounce on walls, initiate a ferocious attack on your enemies eating their flesh and blood.
While standing you can shoot arrows and interact with the enivornment in general. Also while standing/walking there is a greater degree of control.

The game demo serves kinda as a proof of concept. It has been developed as part of a Danish educational program and represents about one months work by 10 people.

It should be noted that the game was originally developed to be controlled using an Xbox360 controller, and as such the help screen you can get by pressing "F1" displays those intended controls (which also should work if you happen to own a X360 controller). The game can however be played using a keyboard, and can be configured from the normal configuration profile.
