Adds several new doodads to the game and 5 new wallpapers (parchment
paper in blue, green, red, white and yellow).
New doodads:
* Crusher: A purple block-headed mob wearing an iron helmet. It tries
to crush the player when you get underneath. Its flat helmet can be
ridden on like an elevator back up.
* Snake: A green stationary mob that always faces toward the player.
If the player is nearby and jumps, the Snake will jump too and hope
to catch the player in mid-air.
* Gems and Totems: A new key & lock collectible. Gems have quantity so
you can collect multiple, and place them into matching Totems. A
Totem gives off a power signal when its gem is placed and all other
Totems it is linked to have also been activated. A single Totem may
link to an Electric Door and require only one gem to open it, or it
can link to other Totems and they all require gems before the power
signal is sent out.
* When playing as the Bird, the dive attack is able to destroy other
mobile doodads such as Azulians and Thieves.
* The Box has been made invulnerable so it can't be destroyed by Anvils
or player-controlled Birds.
* Bugfixes with pop-up modals:
* The quit game confirm modal doesn't appear if another modal is
already active on screen.
* The Escape key can dismiss Alert and Confirm modals.
* Add "Level" menu items to Play Mode to restart the level or retry from
the last checkpoint (in case of softlocks, etc.)
* Switch from otto to goja for JavaScript engine.
* goja supports many ES6 syntax features like arrow functions,
const/let, for-of with more coming soon.
* Same great features as otto, more modern environment for doodads!
* The Anvil doodad is affected by gravity and becomes dangerous when
falling. If it lands on the player character, you die! If it lands on
any other mobile doodad, it destroys it! It can land on solid doodads
such as the Electric Trapdoor and the Crumbly Floor. It will activate
a Crumbly Floor if it lands on one, and can activate buttons and
switches that it passes.
* JavaScript API: FailLevel(message) can be called from a doodad to kill
the player character. The Anvil does this if it collides with the
player while it's been falling.
* New doodad: Electric Trapdoor. It is a horizontal version of the
Electric Door. Opens while powered by a button or a switch and closes
when it loses power.
* The Box doodad will reset to its original location if it receives a
power signal from a linked Button or Switch. So for box pushing
puzzles you can add a reset button in case the boxes get stuck.
* Refactored the Doodad build scripts into many Makefiles for easier
iteration (don't need to compile ALL doodads to test one).
Updates to the JavaScript API for doodads:
* Self.MoveTo(Point) is now available to set the actor's position in
world coordinates.
The Box can be pushed around by the player or other mobile doodads.
It is affected by gravity and can be pushed off ledges.
If the player gets under a box they can bump it up with their head.
