* SugarWiki/AwesomeMusic: [[http://www.youtube.com/watch?v=1tZuNvs-GC4&feature=related The dungeon theme from the first game]]
* ContestedSequel: ''VideoGame/StarTropics II'' was about time travel rather than messing around in the tropics, and some fans of the first game didn't like the change.
* DemonicSpiders: Those freaking gas mask robot raygun alien things in the last two levels of the first game. Durable, damaging, long range attack... argh.
* EthnicScrappy: Baboo. The developers refrained from giving him a goofy accent, but appearance wise he's practically a caricature of a native islander. Fat, wild hair, grass skirt...
* FridgeLogic: If Dr. J is such a good friend to the villagers of C-Island, why is his lab on the other side of a cave full of monsters from their village?
** That cave wasn't always full of monsters. It's suggested that prior to Dr. Jones's kidnapping, it was just an ordinary cave with only tame creatures in it, and whatever kidnapped Dr. Jones also caused the monsters to appear in the cave.
* GoddamnedBats: A lot, especially in the sequel which has numerous flying enemies, enemies invulnerable to frontal attacks, and especially the damn slimes that jump diagonally.
** Although the game actually gets quite a bit of love for an NES CultClassic, Nintendo seems to [[CanonDiscontinuity pretend it doesn't exist]] (thanks in no small part to it [[NoExportForYou not being released in Japan]]). For example, it's the only first-party Nintendo series not to get any representation in ''VideoGame/SuperSmashBros'' (except for a mention in the Chronicle).
** They did see fit to release both games on the VirtualConsole, however, indicating they are at least aware of its fanbase.
* NightmareFuel: If you get too greedy in the first treasure/potion room in the Island Tunnel, [[spoiler:you'll end up drowning in a room full of water with bones and skulls floating in it.]]
* SequelDifficultyDrop: While some criticize the sequel due to the different control scheme (thanks to DamnYouMuscleMemory), there are others who find the game easier to handle for many of the same reasons.
* ShipTease: Mica tells Mike in a backwards message that she'll be thinking of him [[spoiler:just before she returns to her home planet with her people. Think she abducted Mike for their wedding?]]
** [[spoiler:Zoda-X]] at the end of the sequel's 4th chapter.
** The Knight Rider, the boss of the first dungeon in chapter 8 of the sequel, is a major pain to fight. He moves quickly back and forth across the room while you're on a rapidly moving conveyor belt trying to shoot at him with limited range weapons.
** The Dragon, which you have to jump to hit, can fly around blanketing the room in flames, and has to be fought under a time limit.
** Chapter Three runs you through a series of five consecutive dungeons with few healing items. The longest and most difficult of these is the Ghost Village, which also includes several false exits to further vex the player.
** After leveling out a bit for a couple chapters following Ghost Village, the difficulty spikes once more in Chapter 7, with enemies suddenly dealing much more damage and able to hit you from a far greater range due to being equipped with ray guns and other such weaponry.
* TheyChangedItNowItSucks: WebVideo/TheHappyVideoGameNerd makes the argument that the changes in the control scheme from ''[=StarTropics=]'' to ''Zoda's Revenge'' is one of the reasons the game is horrible (at least, in his opinion; he acknowledges in his ''Zoda's Revenge'' review that just as many people disagree with his opinion as agree with him).
