Notes from screwing around in the editor's level tester:
-Trying to pause while using a mega mushroom crashes lua with this error message:

-After using a mega mushroom, the level music stops entirely. Restarting the editor does not fix this, but SFX like the mega mushroom theme still plays.
-The Mega P-Switch appears as a glitchy 1x1 block sprite, cannot be jumped on (you bounce off it as if you were spinjumping), and hurts you on touching the sides.
-I don't know enough math to make my own formulas and test, but I added a Graf whose input formula was the default circle provided and it didn't show up in the level at all.
Side questions:
-Star Coins are said to be tracked by the HUD, but it doesn't automatically show up during the editor. Does it require a LunaLua API?
-Since it's sort of hard to test without making a full world, do the playing card switches toggle everything related to them automatically or does it require an API?
-How are the Player Rinkas aimed? It seems random.
-King Bills, Grolls, and Mega Thwomps can't destroy red SMB3 Bowser bricks while the mega mushroom can. Was this intentional?
-Are redirectors used for anything other than Mutant Vine Heads and Snake Blocks? On a similar note, what are diagonal redirectors used for?
-How do you use Boompers?
-Do the checkpoint flag and checkpoint tape do the same things, and is the multipoints API still necessary?
-Where could I find documentation for the new (and old) APIs? There's some stuff for darkness, autoscrolling, and similar in the handbook, but it clearly isn't all the APIs.
Sorry if this is a lot, but I really like the update and I'm trying to understand it.
