Games are an interactive medium. The final experience is a combination
of player choices and your writing. Unless you're experienced enough to
be able to anticipate how players will react to your game, you need to
playtest your game to find out if players are experiencing the game in
the way you intended.
For the first couple of playtests, your game will just a skeleton. It
will be playable but incomplete. You should use these playtests to find
missing parts of your game and fill them in. You should think of
alternate choices that players can make at different points in the game
and write the text for them.
Just post any changes you want in the comments in the form of more transcripts or using more detailed instructions if necessary.
