 Cave Story Randomizer
 =====================
 
+Todo
+----
+
+- Add all weapons.
+- Add all items.
+- Add instructions.
+- Provide modified Cave.pxm. (When Bubbline or Fireball)
+
 Issues
 ------
 
 - 3 Life Capsules can not be replaced because they appear on maps with 2 capsules. Need label-aware replace.
 - Hell Missile Upgrade uses a unique script and won't be easy to replace.
-- Bubbler (and other weapons?) can't break blocks in the First Cave.
