Fun little concept, addictive too!

The player is prompted to select a category and answer the corresponding questions within a ten second time limit. If they get one answer wrong they fail the category and must choose another. Three strikes and you're out! There is also a challenge mode that endlessly shuffles categories until the strike limit is reached.
The game treats each correct answer as a point and stores the time remaining for every correct answer as the player's speed. Scores are submitted to the leaderboard sorted by questions correct and then by speed.
Thanks to my wonderful wife Carina for help with design, playtesting, and research
