Level 0

• The computer creates a random integer number between 0-100 "the space" which is the distance of the spaceship from you
• You guess the distance by typing in a number.
• The computer write if it is a hit or not

Level 1

• The computer can tell you if your shot was too short or too long.
• The computer will allow you to shoot multiple times.

Level 2

• If the user hits x, s/he leaves the game without finishing it.

Level 3

• If the user presses 's', show the hidden value (cheat)
• If the user presses 'd' the game gets into debug mode: the system starts to show the current number to guess every time, just before asking the user for new input. Pressing 'd' again turns off debug mode. (It is a toggle.)

Level 4

• The 'm' button is another toggle. It is called 'move mode'. When it is 'on', the object move a little bit after every step (+/-2). Pressing 'm' again will turn this feature off.

Level 5

• Let the user guess several times.
• Pressing 'n' will skip this game and start a new one (generate new number to guess).

Allow the user to type
n   - skip this game and start a new one (generate new number to guess)
s   - show the hidden value (cheat)
d   - debug mode 
      (It is a toggle. 
       Pressing once the system starts to show the current
       number to guess every time before asking the user for new input
       pressing again, turns off the behavior.
       )
m   - move mode
      (It is a toggle.
       Pressing once the object will start to move a little bit after
       every step. Pressing again will turn this feature off.)
x   - exit

• Make the size of the space configurable.
• Make sure the enemy does not wander off the training field.
• Give warning if the user shoots out of space.
• Keep track of the minimum and maximum number of hits (in a file or database).

Level

Refactor the code to be nice small functions e.g. for

• moving of the spaceship
• checking the hit
