+# TODO list
+
+## Behavioural bugs
+
+* Ensure that object association is not lost when a Timer is fired for an object.
+
+## Visual bugs
+
+* Make the first frame draw correctly, without requiring a `return true` from the onStep event.
+
+## Ideas
+
+None.

+ 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+ 5. Avoid exposing implementation details on user objects (eg. expando properties)
