A couple of missing optional mini-games, completable


  • Class refactoring (WIP)
  • Sounds (WIP)
  • Help
  • Main menu
  • Control of the drop-down menu with keyboard shortcuts
  • Status leds and buttons on the toolbar
  • A shoot-em'-up mini game after the first encounter with Robin Hood.
  • Whole-screen animations (Intro/outro animations, the ghost room in Avalot's castle, the striking thunder when the player swears too much, etc.)
  • Whole-screen temporary color changes (When Avaroid fires Avvy up from the oubliette, when Avvy wakes up after drinking too much, dusk/dawn, etc.)
  • "Game over" and "about the game" scrolls (They are practically mostly pictures.)
  • Demo mode (If the player doesn't start playing and being idle for a certain time in the main menu, the games starts to demo itself.)

Differences from the original

  • The ScummVM version uses a different font for some of the texts in the game. (For example: Nim.) Maybe they'll be replaced later.

Outstanding bugs

  • The global 'mute all' option in ScummVM is not always working.

Outstanding original bugs

  • The original game doesn't update the little icon which represents the direction Avalot is facing if you control him with the mouse by clicking on the background. At the moment, this bug is also present in the ScummVM version of the game.
  • Saying 3 times insanities while in bed duplicates Avvy...
  • After you rescued Geida and leave the screen in front of the Baron's castle to the right, Robin Hood won't come to take the girl away. You have to go back to the screen to trigger the event. There's a missing 'also line', which causes the bug.
  • There are similar problems with loading Avvy's movement speed to the savegame loading bug. These occur for example when you leave the cupboard in de Lustie's castle, or when you got back from the shoot em' up in Robin Hood's forest.

Fixed original bugs

  • There was a bug in the original engine that caused the internal timers of the game to mess up when a savegame is loaded. The problem was that when you loaded a savegame, the engine set the internal timers for the room by default and after that loaded the timers you saved when you saved the game. For example in the first room, if you made a save while Avvy was sleeping and loaded it back, you may have noticed that his wife, Arkata's timer was messed up: she shouted every time she should counted from the time you saved, and shouted every time the room's newly set internal timer told her to do so. Now it is fixed: if you load a savegame, the engine only loads the saved timer, and leave the default one for the cases when you enter a room newly.
  • The original game didn't load properly the state of Avvy's speed (walking/running) from a savegame: The little yellow dot at the bottom of the toolbar was always set to "walk" state, even if at the moment of the saving Avalot was currently running. In the ScummVM version, this bug is fixed.
  • In the original, when you play the harp in the abbey, the game doesn't always hide the mouse cursor. In the ScummVM version, it works properly.
