TO DO
-----

general:
- drop-in Zip file support (for level and artwork packages)
- internationalization / localization support (local language catalogs)
- support for different (higher) screen resolutions / resizable window
- local multiplayer mode with auto-player-focus
- support for playing network games for the SDL version (Windows, Mac OS X)
- graphical user interface for playing network games

game engine:
- more game elements like transporters
- change BD style amoeba behaviour from "only in BD-elements-only level"
  to configurable in the level editor (-> "player blocks amoeba or not")

other:
- makefile target for installing the game
- updated version of the man page
- decent documentation in HTML
- more levels (that's the point where *you* can help out! :-) )


TEMPORARY NOTES:

DC2:
====
Todo:
- not-round walls
- growing wall: check partly destroyed growing wall (non-steel)
- multi-player level: do not end game when first player enters exit
- amoeba speed (see tutorial level 15)
- fix shield normal/deadly time issue (shield deadly also adds "normal" time!)
  (see tutorial level 28)
- yamyam starts with small pause (R'n'D: immediately starts moving)
  (see tutorial level 30)
Done:
- slippery walls (for gems)
- destructible and indestructible switches for switchgates and timegates
- landmine that can be snapped
- growing steel wall
- exits that disappear after using
- new keys and doors (white key, white door, fake door)
- magic wall (pearls, crystals)
- slow quicksand (slow: normal => fast quicksand added)

other:
- end game with tape requester -- do NOT wait for key like in 3.2.3
  => done
- allow <space> key for confirm requester (like "tape saved!")
  => done

whole screen customization: (as artwork set definitions)
--------------------------------------------------------
- different border backgrounds for each screen (but at least menu <-> game)
- free game panel dimensions, especially:
  * different playfield dimensions
    + 17x17 (RND)
    + 20x12 (EM)
    + 19x14 (DC)
    + 20x11 (SP)
  * EM/DC style status line
- door requester done differently (envelope style, scrolled in from right, ...)
- if not 17x17, fade whole screen between menu and game

!!! EM: !!!
===========
- adjust graphics and sounds for new EM style doors and other new EM elements!
- add GIC switch to explicitly use the EM style graphics engine

!!! BUGS REVEALED BY ALAN'S "windows": !!!
==========================================
bugs & inspirations:
- 100% CPU in game even when not moving (unneeded permanent mask redraw)
  => argh! it IS needed -- at least the player is redrawn every frame... :-/
- fading out from main menu to game with game mask
  => fixed
- reverse font in editor (probably not a bug -- check this)
  => todo
- tell Alan how to use (define) an UPPER/lower enabled font!!! (see editor)
  => todo
- check preview.tilesize in 3.2.3
  => seems to be OK
- check possibility of PNG mask with alpha channel for game mask! (-> RoX!)
  => R'n'D 6.0.0 ;-)
