That was boring.
+It was quite interesting at the beginning;
-Awful and boring backgrounds;
-No ability of decidion;
I love this genre, because playing it is really fun: it usually has different variants of walkthrough and a bit of logical element. This game has nothing to do with this things.
Well, the main character's design impressed me. The protoss too. But the backgrounds were sooo damn annoying.
Why the hell did it have only one way of decidion? Even if I've chosen to do something what is "wrong" the game had to continue but, for example with the character's health lower or so. This is the main thing in the genre.
You should work hard to make a nice game. As it's your first attempt of creating a choose-your-adventure game, I'll put you a 2 (3 is too much, I think). So work, train and try.
