Has its faults...
Nothing special, but some improvements could be made. Like spelling gingerbread correctly, drawing better gingerbread men and such. But as the name suggests, this is a demo, but you're better of posting in the N.G. Mag Alpha section until its complete.
In your final game, try to make ammo, instead of having unlimited shots. Also, learning how to create a custom menu might help, as clicking play makes and kills a ginger bread man.
Have a 5, though its not great, I want to make sure its protected.
Congratulations on an OKish game.
