The Iconoclasts/YMMV


 * Darkness-Induced Audience Apathy: Most of the characters in Iconoclasts, save for Robin, Mina and the various ChemiCo Contra workers you encounter, are jerks, which makes it hard to actually care about their fates. The majority of the people you encounter are jerks or are very selfish and ungrateful. Robin's brother Elro is a Knight Templar Big Brother whose attitude towards her borders on stay-in-the-kitchen sexism (not to mention his decisions directly result in much of the game's plot), while Royal's legitimately tragic arc is undercut by his arrogant personality. Even Mina has an episode in which she undeservedly lashes out at Robin; and since she's mostly a Heroic Mime saddled with But Thou Must!, you can't really call anyone out.
 * Good Bad Bugs:
 * Ground-pounding down a slope and jumping off of it allows Robin to maintain speed from sliding down it until she stops moving, making her move at max speed even without any Fleet Foot tweaks.
 * Air-swimming is a major part of the game’s speedrun, since it can be used to clip through walls and skip large chunks of the game. In the current Any% route, it's used to get from the end of Isilugar all the way to the final boss's chamber, skipping two-thirds of the game.
 * Scrappy Mechanic:
 * Without at least one Spinner perk equipped, Robin's wrench just barely can't charge itself with a single spin. Either you deal with having to spin twice every time you need to charge up (which you'll be doing a lot) or you spend one of your three tweak slots on something that doesn't have much benefit outside of charging the wrench.
 * The Boss Rush modes don't let you select your own tweak loadout, instead giving you three Iron Hearts. While this is intended to counteract the lack of health pickups (and possibly to make speedrun times consistent), it also prevents you from using the weapon upgrade tweaks or the dodge roll/double jump, which would be just as useful as the shielding.
 * That One Level: The Tower. It starts off as a No-Gear Level (though Robin retrieves her wrench pretty quickly) and then turns into a vertical maze where the goal is to free Mina and Elro and then collect three keys to reach the top. Its annoyances include enemies that sap your wrench charge, having to crawl slowly through many air vents, needing to manage several elevators to get around, and getting periodically ambushed by the Silver Watchman. It's also a pain to collect everything in, since you need the Usurper Shot for two items, and the map isn't very helpful (it displays the inner rooms as being accessible from both above and below, even if they aren't).
