Rename ._game_state to game_state for consistency with engine and since everyone and their dog has access to it. :)

| 60 Many moons ago, an evil nine-tailed kitsune, a fearsome fox god, ruled the | |
| 61 land. | |
| 62 | |
| 63 It had many powers — the ability to shape shift, turn invisible, control | |
| 64 the elements. Its powers came from its majestic tails and the kitsune | |
| 65 guarded them ferociously. If any fox attained eight tails, it would battle | |
| 66 the kitsune for domination of the celestial world. To prevent this, the | |
| 67 kitsune stole the tails of all the foxes it encountered. | |
| 68 | |
| 69 The evil kitsune challenged every fox to a haiku contest. But the | |
| 70 competition was not fair, and the kitsune cheated every time. When it | |
| 71 defeated the poor fox, it stole its tail and threw it to the four winds. | |
| 72 | |
| 73 The kitsune stole your tail. Now it’s time to get it back. | |
