Spheres 2000 2.01
Spheres 2000 challenges you to guess the right word before the computer beats you to it.
In the demo, words are of 5 or 8 letters in length. Guess any word, and if you selected a letter that is in the final word, the letter turns yellow. If it's in the right location, it turns blue.
A nag will interrupt your game if you don't have the full version. My only complaint was that some of the words were... well, strange. "Willy"? "Kickapoo"? Kind of strange. The quicker you guess the word, the more points you score. Good luck.
