jockslap - this is a shareware game. A shareware game is distributed free of charge but has limitations. You need to purchase a license to get the full game. What you are thinking of is freeware, which is completely free.
The "perfect" and "good" words get in the way when trying to play and distract from the game. Perhaps if they were smaller or didn't pop out it would be better.
