Some tweets, made playable, are not playable.

Feeds this playable dungeon:

When the rooms aren't linked, it usually becomes impossible to complete the dungeon.

So far, the interim solution has been to delete offending tweets.

Possible solutions on the dungeon generation side:

• Remove a room and its content if no paths to it are generated and/or found.
• Allow paths to turn through 90 degrees, make a path to 2 rooms from a point that's in a line from both.
• If a room is isolated, try adding another room, then generating paths.

yeah - I hope to fix it.
I'm going to make a temporary 'fix' which is just to up the number of rooms placed, but it should get real treatment at some point - when I have time
though feel free to make a PR if you have any bright ideas
