This game works only on Linux as it uses pyxhook for input which is a Linux only version of the Windows pyhook. The file pyxhook.py is the Copyright (C) of Tim Alexander dragonfyre13@gmail.com 2008.

• OOP concepts have been used extensively.
• One can increase/decrease the sleep time in game.py if the terminal screen flickers.
• The floors are randomly generated (even for the same level) using a kind of backtracking algorithm ensuring the freshness of the game.
• The stairs are randomly generated and care is taken that there is atleast one path from the player spawn position to the princess.
• The differences between the levels are:
  • There are more Donkeys in the higher levels (1 in level 1, 2 in level 2, 3 in level 3).
  • There are more Fireballs in the higher levels.
  • There are less Stairs in the higher levels meaning less paths to the princess and more difficulty.
  • There are less Coins in the higher levels meaning a lower score.
• The user has complete control over the number of donkeys, the number of fireballs and the number of stairs. All the three can be reset changing a maximum of two variables each. This is possible because there is no hardcoding.
• Multiple Donkeys make the game more challenging.
• The Stairs break if two Fireballs move over them at the same time or if the Player collides with a Fireball on a Stair.This ensures a more challenging game and the player has to be real quick to finish it.
• If the Stairs break, the game is as good as over and the player has to quit.
• One can change the number of rows and columns. To do this, change the ROWS and COLUMNS values in the game.py file.
• The Donkeys die if the Player collides with a Donkey. This is done so that the game is not too hard.
• Care has been taken to ensure keyboard responsiveness and lag mitigation.
• Comments have been provided in the sourcecode where ever necessary.
• Jumping using the spacebar may take a while to get used to. If the user has pressed d and then space, then the player jumps to the right. Similarly for left. If it has been more than a second since a user pressed a or d, then on pressing space, the player jumps vertically.
• Colors have been added.
• The Player gets bonus scores when he performs some specific actions like killing a Donkey or rescuing the Princess.
