Perihelion II is a game that had my full attention for 3 months.
An asteroids-based game with extensive options and customizable ships. Fly missions and unlock obstacle courses,
choose a color, choose a flametrail, choose a ship. All features from Perihelion are included.
This won in the Games category of the Regional TSA contest, and also won Best Overall for the entire contest.
From there it went to state and won me a blue ribbon!
