In the game you play Mario and your task is to free his brother Luigi, who was captured by evil Bowser.
Mario is controlled by Keyboard or Gamepad. The control is easy. Use arrowkeys to walk, Space (or gamepad-A) to jump and CTRL (or gamepad-B) to run/fire. After reaching a castle the game is auto-saved and can be continued at any time by clicking on "Load Game".
The game has 25 different levels and 10 different types of enemies. There is also a level editor,, so you can create your own levels (read "Editor.txt").
