-# gmtk-2025-loop
+# doodle game concept
+A game about using your finger/mouse to draw circles around moving game objects.
+It works by instantiating an `Area2D` node with a polygon collision shape, and can probably
+also be mildly modified to draw level geometry dynamically.
 
-GMTK game jam, 2025. Theme: Loop
+In either case, the challenge is taming an otherwise automatic system.
+Objects move on their own. You only control the pencil.
+
+## Current questions
+* Should it be about capturing only the correct game entities?
+* Should it be about drawing level geometry to guide game entities to a goal?
+
+## Current definites
+* Doodles-in-the-margins lined paper aesthetic
+* 2px outlines, simple colors
+* Can likely use shaders to make it appear slightly sketchy and animated
