These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anticlimax Boss: One shot, or even ramming, is all it takes to splatter Xoxx's head after you destroy his backup time washing machine in the Gold Edition.
Sidetracked by the Gold Saucer: The Tetris-esque Tetrix minigame. The Steam release of JnG Gold even has an achievement for getting 10,000 points, a nearly impossible task due to the differences in pieces from normal Tetris.
That One Level: In some levels, you have to go underwater and must encase your ship in a special shell. This severely limits your weapon slots and upgrade options. When you could attach many more things to your ship just before, being forced to take such a reduction in firepower is annoying.
Level 3 has tons of enemies that just love to zoom and swoop around unpredictably, in a game where Collision Damage can and will kill you in seconds.
