Beta 4 - The Great Escape Easy

[Toybox]

I just ran out of ideas! There is a different sort of clue in the same room in, um, Normal I think, based on labelling levers and coins, but it is not so elegant. I could

paint

pictures of keys and so on on the walls, but that would just take too much space (I'd need a full room for it, instead of a few bricks!).

But with extra BBB's, and since it's a multi-coloured key, I don't feel it can be misleading. I'll see if I can think of something else.
