Tweaked level 16 a bit - shortened range, added a quicker way to change monster probabilities per type ( exciting, no? )

Trying to figure out a mechanism I like for non-buildable spaces. Webbstre suggested mud, and I like that ( or quicksand ) but is mechanically problematic. If a brick is half-sunk in quicksand, can you pick it up? What if only 10% sunk? And if you can pick up and re-place objects on it, does that perform its intended purpose?

May have to do lava or something - a mechanism that performs irreparable damage. Leaving things there results in destruction. Given that you can throw objects it is hard to prevent you from tossing something there, so contact or placement within the vertical band has to be the limiting factor.

Spiky trap ground that stabs things? Thorns? A crusher that smashes stuff? (hmm) Timed explosives? ( volcanoes? geysers? ), thinkety thinkety.

Need to play an 'error' sound when trying to grab burning objects and failing. Or a red exclamation particle. Or both.

Also, revising thoughts on 'almanac'. Thinking of having a spotlight shining on a little walking version of the monster, maybe some goofy french music, and then details spew on the bottom of the screen in silent-movie style title cards.
