An idea for the wiki: Document the levels. I'm thinking along these lines:

1. What family group the level is a part of.
1a: If known, which minerals result in the creation.
1b: Does the color of the level's icon match the color of the minerals needed to build it? Is there any control besides mineral color?

2. Expected monster families
-- Some levels generate lots of jelly creatures.
-- Some generate lots of wolf creatures
-- Etc.

3. Expected reward types
-- Some generate minerals
-- Some are crown heavy
-- Some are heat heavy
-- Most will be mixed

4. Expected difficulty
-- This isn't exact, and there is depth variation
-- Even without that, some levels may really favor multiple people fighting together, and be really hard for a "level appropriate" soloer.

5. Whether or not there are any "variations" in the level.
-- The overgrown path from rescue camp to Haven has at least two varieties, as the one that killed me the first time (lots of turns, with lots of guns and spikes at the turns) wasn't there the second time (only a single stretch of spikes and guns).
