Mastermind (logic game)

Last year I started learning programming at school.
At the end of the school year we had to make some game as a "end of term work".
I have choosen Mastermind.

It is my first game in Delphi, it uses its default components.
It is very simple, so be sorry, if you expect something special.

Sorry, I forgot to include the game
Now it's there, please tell me, what do you think about it.

Seems to work fine. I remember playing this game a lot, except with words except of colors, it was quite addicting. I think you did a good job.
