More on stairs and monsters

I think that, further to the comments on my last post, I won't bother, for now, allowing monsters to follow the character up and down stairs.

As you'll probably have noticed, posting is light at the moment. I've decided to take a break for a few weeks from development.

Stairs and Monsters

I'm currently writing some code to allow monsters to travel the stairs with the character, following the behaviour of those in Crawl.

As implemented, all adjacent monsters will travel with the character, as long as there is room on the destination level for them to do so.

However, I'm nearly sure that (from last time I looked at their source) Crawl puts a limit on the monster types that can come up stairs.

Do you think this is a better solution? And if so, what criteria should be used to determine ability to travel up stairs? (I don't have any Dalek monsters alas)
