Think Quick!

Think Quick! is an early educational puzzle/strategy game. In order to win, you must solve the puzzles found in Castle of Mystikar to create an enchanted knight that will defeat the dragon. Solving the puzzles and opening the proper doors is made more difficult by the presence of slime worms, which will either sleep, if you feed them a flower, or swallow you whole.

Not only did Think Quick! allow you to choose which character you play (boy or girl), but there was also a level editor to allow you to create your own puzzles.
