Lore Engine v0.3 has been released!

Changelog

Second vocal tracks have been properly added in, and can be toggled from the Chart Editor.
There's a marvelous hit window now.
The song name and time remaining are now both shown in the time bar by default.
StepMania style judgement animations have been added
Colorblind filters have been added for deuteranopia, protanopia, and tritanopia.
Note scale can now be tweened using the noteTweenScaleX and noteTweenScaleY Lua functions.
There is now an option to make the head icons smaller.
The head icon bopping animation can now be toggled between Lore and Psych, or disabled entirely. (They can also be overridden in Lua with the onHeadBop callback.)
New countdown sprites have been added.
The camera now properly zooms prior to the opponent singing the first note. (If there are any animations this breaks, just set the property of camZooming to false in Lua.)
Shaders have been added back in, but you can only use them from source.
There's a new variable you can set from Lua called topTimeSignature which determines on what beat the camera will zoom.
If you compile the game in debug mode, text saying NOT REPRESENTATIVE OF FINAL VERSION will be shown during gameplay.
You can now see the arrows in the rating offset screen.

The FPS counter is now in the proper position if you have it set to bottom left and resize the window.
Blammed lights now work properly on songs other than Blammed and stages with a very low camera zoom.
The lane underlay now loads after cutscenes finish.
