Just as the game gives several combinations of unique abilities to try, so too does the game account for several things players can attempt.
- If you manage to get severely injured in the tutorial (which is hard to do unintentionally) you won't be able to go below 1 health, meaning you can't die. This changes the conversation with Savant after the level, where he reminds you that the rest of the game won't be so forgiving.
- It's possible after the first time you've completed the mission to beat the Really Large Robots level without piloting one of the Virs mechs. This will cause Boki to complain about the level's difficulty, and Savant to hint that you should have just used one of the robots instead.
- 1-5, "Swordfighters", which requires the use of the Blade made by Lightning + Quick, if Blade uses are exhausted before the point it's required, a target will arrive from the bottom of the screen to deliver more Lightning and Quick.
- If you're focusing on getting the minimal damage golden stars, after completing the first world, Savant will commend you for your skill, but remind the player that it's just cosmetic and there's no reward for doing so, although they do unlock the Custom modifier for each level.
- A humorous one - After you defeat the 2nd boss in the woodland level, should you decide to quit to the main menu rather than continuing, Savant will complain that it's not heroic to just walk away while everything's on fire.
- If you let Boki get squashed after Yolomacho's fight, she simply goes silent at the cutscene afterwards. If you're playing as Savant instead, he simply teleports away before resuming the cutscene as normal.
- The whole Arikan battle is chock-full of these.
- Beat Arikan with any cheat, and they'll call you a dishonorable scum. Lose to them anyways, and they'll berate you further.
- If you beat Arikan with a Virs, the ending dialogue changes to "You dishonorable scum!"
- Should you successfully defeat Arikan without taking damage, there is a special line of dialogue.
- Lose to Arikan using any Construct (modifiers allow you to play as certain enemies), and they'll call you a traitor.
- Start a battle against Blade Arikan with a Yolomo of the Sun Fist, and he'll challenge you to see if fists are better than swords.
- Return to the level select after losing to Arikan, and they will mock you.
- If you fail to complete the brief Button Mashing sequence at the end of Drill Arikan's fight, she'll chide you for your lack of resolve and restart the fight.
- The ways you could refuse Arikan's challenge yield interesting results. Here's a list of things you can do to get different reactions:
- Shoot them, and they'll ask if you'll fight with your hands.
- Jump on Blade Arikan, and he'll get pissed off and call you immature.
- Kick Blade Arikan, and he'll ask if you'll fight with your feet.
- Wait for too long, and they'll get impatient.
- The exit game messages:
- If you exit the game immediately after running it without doing anything, Savant will point it out and ask if you ran it accidentally.
- If you exit the game after downloading an update, Savant will say he expects you only did so in order to apply said update and come right back.
- One of the messages displayed when you exit the game is actually the exact amount of explosions the player caused during their session of play.
- If you have not played as Savant for more than three sessions, one of Savant's end texts has him complain he's being sidelined, just because the game's called Copy Kitty.
- If you exit the game with cheats enabled, Savant may chastise you for using them, stating that it hampers the effectiveness of the combat simulation.
- The Throne Gehligrukai's tune actually changes to fit the music currently playing. Yes, that includes the Arikan-only battle music that doesn't appear anywhere else by default.
- If you've died more than six times to Hypercube Krijyl, she'll count how many deaths you've had so far, and insinuate that among the vaporized atoms that were your body, she found a high concentration of salt.
- Speaking of Burst / Hypercube Krijyl, it has a special win condition that involves Mirror, allowing you to reflect one of her lasers back at her, immediately destroying the boss. Its hard mode upgrade, Hypercube, is also vulnerable to this, but is pushed to the third phase instead of dying instantly and gives special dialogue. Note that without cheats, this is only possible in Marathon mode, though the level directly before it has the power required.
- Speaking of consecutive deaths, if you've failed to beat either form by your fifth attempt and decide to quit altogether, she'll mock you for running away in the middle of combat, call you a chicken, and expresses disappointment in your resolve.
- A more positive scenario happens in reverse if you manually decide to quit Supreme Thremnat since the unique death screen disables the option. Boki will be tired out by the fight and decides to come back later, but vows she'll win eventually.
- The dialogue in the mission after Penguin Vault varies depending on how many alarms you've triggered. The dialogue in Demolished District, a whole four worlds later, draws from that as well — if no alarms were tripped back then, Boki will claim it's time for super spy Boki again!
- If you defeat a boss as Boki on low health, even under Death by Poke modifier, instead of the usual victory animation, she will plop down to the ground, exhausted.
- After defeating the Prison Yoggval, most players would have the Radio Pulse weapon equipped, which plays into the cutscene afterwards where Boki realizes that the weapon causes radio interference and then she swaps it out so she can talk to Savant. However, if you quickly swap out or drop the weapon before the cutscene starts, it skips ahead to Boki and Savant's conversation as normal.
- After beating Maszylg, Boki uses the giant mace she copied during the fight to destroy the shutter blocking the exit. If playing Marathon Mode, which lets you keep weapons between stages, the mace retains the ability to break shutters, letting you skip many puzzles.
- At the start of Mission 6-2 Cell Block (6-8 in Hard Mode), the first alarm will bar the entrance where you spawned. If you've already triggered the alarm and die before turning it off in Marathon Mode or using a Custom Weapon, Savant will warp in and physically teleport you out, wondering how you managed to do that through the garbled transmission.
- If you opt to retry Penguin Popper, Savant wonders why Boki would want to, but she (and by extension, the player) is having too much fun.
- A good method of avoiding attacks from pilotable enemies like Virs and Oovoh Saucers is to just use them as a Goomba Springboard while firing down on them. However, in the final world of the game, you encounter a somewhat-Oovoh-like piloted cannon turret, and if you try the same trick on them, the pilot will simply close the cockpit and ram Boki into the ceiling.
- If you retry "Frozen Fiend" (a Yoggval fight where the boss has fire powers), Boki will complain that the level name is completely misleading. This prompts Savant to change the level title to "Fiery Fiend" instead.
- During World 4, Dynamite Terebryll will appear in some stages to distract the player, and on occasion must be fought off. Later, when battled as a proper boss, it starts with its health bar damaged, since you've already dinged it up previously.
- Just before the battle with Phoenix Yoggval begins, there's a very brief section where the player has to walk up and touch the artifact powering it, which many players will do without a second thought. If you wait long enough, Boki will express disbelief that she has to activate such an obvious trap, prompting a But Thou Must! response from Savant.
- There are certain Virs-related power-ups that allow Boki to shoot small homing Spheres of Destruction: Light of Ra, which shoots balls of light, Shadow of Apophis, which shoots balls of darkness, and Chaos of Akhetaten, which shoots both. If you happen to pick up both Light of Ra and Shadow of Apophis (which isn't possible in the main campaign and therefore can only be done in custom levels), they'll combine and become Chaos of Akhetaten, saving you an extra weapon slot.
- Remember that awesome finishing combo Boki does to Exgal, Superboss supreme? Well, if you're lucky enough to find all the Ulsevs' powers in Pandemonium, you can use it. Yes, Vestige of the Lost is a legitimate attack. See it in its glory here
. - Invert Krijyl has an exclusive move if fought as Savant (possible by creating a custom level from Electric Death and playing as Savant). It's the same as its slam move it uses as Boki, but it turns upside down to crush Savant against the ceiling.
