Analysis
The success criteria I created for my program are the
following:
➔ Users can authenticate
➔ Users can create an account
➔ Both players have their scores added / subtracted from
their score each round WITH a reason why.
➔ Total score of the winner announced at the end
➔ Winner of the game is announced
➔ Rounds counter functional
➔ Tiebreaker round functional

the round WINS! Good luck. Type 'next'
"The rules: Each player will roll 2 dice per round. If you get two of
the same number you can roll an extra dice :), if your score for
the round is even you get 10 points extra :D, however if it is odd
then 5 points are taken. Your score can only be <=0 and there are
5 rounds"

Evaluation
How successful was my program?
My program was overall successful because most components of
the code were able to function properly, allowing the game to be
played to the end of the script. The authentication script was a
success with users having the ability to have their usernames
and passwords saved to the database, permitting them to quickly
login next time they play the dice game. Moving on to the game
itself, users are notified on what round they are on, their current
scores, and who the winner is. Major components like these are
what makes the game effective. Also, bonus rolls are available if
the user rolls 2 equivalent numbers. And if the users score the
same at the end of the game, there is an additional tiebreaker
round to decide the winner. Even though there are a few issues
with the script, for example line spacing, player 1’s signup
system, I’m certain that this game comprises of all the
requirements needed for a two-player dice game: The login script
was a success, the instructions and key messages were readable,
the dice was unbiased, and lastly, the score counter summed the
scores correctly.
New skills I have developed
Working on this project has really increased my confidence with
coding in general. I have learnt many new reserved words which
I decided to use in my project. I also learnt how to use lists, which
allows me to display certain letters from a variable, simplifying
the code. Another thing I have learnt from programming is how
to link text files to my code for users and passwords. Lastly, I
have learnt what Pseudocode is, why it is used, and how to use
it. One key thing that I have gained from this project is a better
understanding of programming concepts.
