I got the most annoying bugs fixed, and in the "restructuring" branch, I'll also be able to use the same controllers/shooters state machine plug-ins for both runMe (the interactive playtest tool) and the final SchoolTest ROM.

I can choose between regular background and debug console output too. InspectorWidget, on the other hand, is messed up with some text. I'll be able to resume level design...

well as soon as I figure out why the level editor is stripping out all the dynamic objects. (not that it's so surprising, as the last thing I tried was to remove dynamic objects that were out of the level's boundaries).
There are other oddities linked to incomplete port to the latest devkitpro/devkitarm/libnds, imho, such as
[fixed] no sound playing in new builds of runMe[fixed] no EFS found for SchoolTest
