+'gunnailp' observed differences (from notes by trap15)
+
+   - Different introduction scene
+   - Many unique enemy types that ended up unused
+   - Tweaked enemy attack patterns
+   - Tweaked boss behavior and attack patterns
+   - Dramatically different stages (and only 7 of them):
+	  - Stage 1: Became Stage 5, very different layouts
+	  - Stage 2: Became Stage 7, with mostly slight enemy layout changes
+	  - Stage 3: Became Stage 6, almost the same as final
+	  - Stage 4: Stayed as Stage 4, with very minor enemy layout changes
+	  - Stage 5: Entirely unique stage, majorly reworked to become final Stage 2
+	  - Stage 6: Became Stage 3, many enemy layout changes
+	  - Stage 7: Entirely unique stage, majorly reworked to become final Stage 1
+   - No ending, instead loops forever
+	  - Loop has extremely fast bullets
+	  - The difficulty seems the same on all loops
+   - Player's blue shot has a wider maximum and minimum spread
+   - Player's main shot hitbox is symmetrical and wider than final
+	  - When the hitbox was shrunk for the final, it was only shrunk in one direction, making it extended to the right
