I can tell you why there was never a "Chapter Two".
This game stars a young female unicorn, and an old male troll. You control them both, with the unicorn running and the troll attacking from on top of the unicorn. Evil has taken over the land, and your job is to ride around and beat the evil out of the beings that have been taken over by the dark plague. You don't kill anything, you just smack things with your staff or magic until the plague is gone and they go back to the peaceful beings they were.
The big problem I have with this game is that I don't know who it was realistically geared towards. By the title, the graphics, the lack of violence, and the simplistic gameplay, I would assume that the game was for a younger audience. But this game gets incredibly difficult at parts. Your characters are weak, and they get "killed" (of course they don't really die) easily and the level gets restarted. Since I wasn't having much fun with the game, and it is tediously difficult, I used cheats frequently to get to the ending. That's right, I used CHEATS on A UNICORN GAME. A low point of my life? Yes, one of several.
Other than that, the gameplay just isn't fun to begin with. The controls are simple yet tedious, it's hard to hit anything without getting hit yourself. The sounds are bad, especially the one liners that your characters bicker towards each other, which is like 3 different lines repeated over and over.
The best thing about the game is the graphics, which aren't bad. The story itself is also tolerable, although nothing incredibly original.
