    - Often generate monsters when opened.
- Moss (slidey?).
- Huge number of counters, counting all sorts of obscure actions.

	- A ridiculous number of Achievments?
- Weapons:
	- Sandblaster gun.
	- Flaminator.
- Special one-off monsters.
- Bikini Whales can open up Disco levels.
	- On Disco levels, there's a special item in the centre, surrounded by a
	  circle of dancing Bikini Whales - to get it you have to get through the
	  circle without touching a Whale.
- Cultists (of brown, blue, pink).
	- When a Cultist first appears in the Player's field of view, it will
	  immediately disappear (leaving a Puff of Smoke).  The next level will be
	  a cultist level (if you don't kill the Cultist before it disappears).
	- Cultist levels have a big bonfire in the middle, *lots* of Cultists (all
	  attacking the player), and a Head Cultist.
	- As long as the Head Cultist is alive, more Cultists will be generated.
	- The down stairs are beneath the bonfire.
- Chess level.
	- Level is a chessboard.
	- Monsters are chess pieces, with two invisible player monsters which move
	  the pieces as they would a real game of chess.
	- Player is stuck in the middle and will have to get to the exit, which will
	  be randomly generated under one or the other King.
	- If the player can be 'taken' by a piece, they will be attacked by that
	  piece.
- Secret doors/rooms.
- Garden level.
- Fungus monsters (toadstools, giant stinkhorns etc.).
- Procedurally-generated side quests.
	- Will need quest-giving characters.
- The eyebrow guy from the story screen should appear again.

- Chance to miss the final level, with the result that there are another 50(?)
  levels, and you eventually reach China.
- Romance.
	- Kiss button.
	- 'alone time' button.
	- Pregnancy (player's gender is randomised at the start of the game)
	- Falling out with a lover is *bad*.
	- Stalkers.
- The chance to become a god, with absolute freedom (how on earth do you
  code/define that, though?).
- Cooking.
	- Special cooking utensil items (gas stove, blender etc.).
	- Special cooking tiles (oven, fridge, pizza oven etc.).
	- Combine anyhing, with varying results.
- BabySpiders can grow up to become Mummy- and DaddySpiders, etc.
- Cats and Dogs fight each other.
- Name items to identify them.
	- Can only name things once though, or it would be too easy.
- Cats are special.
	- Cats can be placated by saying "Hiya Puss" to them.
	- If you save a Cat's life, no Cats will attack you from then on, and
	  they'll try to return the favour.
- Special level: Faery.
	- Bigger than a single screen, i.e. scrolling.
	- Full of Faeries and Fairies, and Banshees and Bean Nighes.
	- Only one level: you can't dig down, and there are only stairs back up the
	  way you came.
	- The only place to find Fairy Dust.
	- Has a single special item which can only be found there (but what is it?).
	- Maybe get there by getting surrounded by Fairies/Faeries, who steal some
	  of your stuff (and put you to sleep?).
- New story screen.
