This game is my interpretation of the all-time classic arcade game Asteroids. Although it plays a little differently, it has all the components of the original game. The rocks are stationary, but — if destroyed — split into two smaller pieces. You can either destroy the rocks via missles or by just flying right into them.

Controls

  • Left arrow key tilts the space craft to the left,
  • Right arrow key tilts the space craft to the right,
  • Up arrow key propels the space craft,
  • ‘Space’ launches a missle.

After having programmed Jic-Jac-Joe — where you need to connect three pieces —, I now programmed Connect Four (four pieces).
This version — although it does not have a computer player — includes win detection.

Controls

  • Left-clicking puts your piece where the mouse cursor is positioned,
  • ‘Escape’ restarts the game.

Caesar Cipher

This program lets you write a short line and encrypt it using Caesar’s Cipher. It shows the two prior and next rotations, as well as the current encryption key.

Usage

  • Normal letters let you type text,
  • ‘Backspace’ lets you delete the last letter,
  • ‘Tab’ sets the encryption key to zero,
  • ‘Escape’ toggles if key and other rotations are shown,
  • ‘Return’ toggles if special characters (characters that are not contained in the standard alphabet) are displayed,
  • Up arrow rotates up (encryption key decreases),
  • Down arrow rotates down (encryption key increases).
