đŚ One step, two steps, suddenly you donât fit
The floor blinks, you take a cautious hop, and your avatar stretches like warm gum. Another step and the camera climbs to keep up while the tiny starter platforms begin to look like souvenirs. Obby: Grow with every step isnât a polite course you memorize once; itâs a shape-shifting duel between your reflexes and your own expanding hitbox. Every footfall adds height, width, a smidge of momentum, and a surprising amount of comedy. You will bonk your head on a door you walked through ten seconds ago. You will bounce from a spring that was helpful when you were small and becomes a catapult when youâre, well, a skyscraper with shoes. Itâs parkour with a biological twist: movement as puzzle, growth as risk, and the finish line as a dare.

đ Size is power and problem at the same time
Growing changes verbs. At small scale, youâre nimble, threading fences and landing on buttons the size of cookies. Mid-size turns you into a confident jumper who can clear gaps with a casual toe-flick and shoulder-check pushable blocks into place. Giant mode makes long platforms trivial but introduces crimes like doorframes, low fans, and laughably tiny elevators that squeal under your heroic mass. Routes you ignored as a bean become necessary detours as a behemoth. The smartest runs treat growth like a resource to spend and a mess to manage: shrink when precision calls, bulk up for brute-force shortcuts, then ride that awkward middle where the course canât decide if it fears or loves you.

đ§ The geometry of getting bigger
Every obstacle teaches a different lesson about scale. Collapsible bridges count steps like a petty accountant; sprint across while light and youâre fine, trampling them as a giant turns the bridge into a memory and you into a legend midair. Rotating bars ask for timing as a shrimp and patience as a giraffe because your head will meet their orbit sooner than your feet do. Fans flip from âgentle liftâ to âyou are a kite nowâ depending on your weight; use a quick micro-shrink on the approach to catch the perfect updraft, then grow again mid-flight to carry momentum into a safe landing. Even the camera is a collaborator, zooming out to honor your newfound altitude but never hiding the next decision. Learn the map at one size and it becomes a different game at the next.

đŞ Shrink pads, growth coins, and spicy choices
Youâre not at the mercy of the meter. Shrink pads hum in cool blues, slicing a chunk off your scale so you can slip through vents and nail tight wall-jumps. Growth coins glitter with exactly the kind of temptation that ruins good plans and wins speedruns; grab one and your stride length spikes, your jump clears triple, and all those âtoo farâ platforms start looking friendly. The magic lives in cadence. Shrink to align, grow to commit, and chain both within a single jumpâtap a shrink pad at takeoff, snatch a growth coin midair, land colossal on a breakable wall that only bows for giants. The course rewards players who treat size like rhythm rather than a static number.

đŻ Movement that flatters curiosity
Inputs are clean: a crisp jump with generous coyote time, a responsive double jump that scales with your size, and a dash that respects momentum without becoming a teleport. Wall-jumps read true and feel different at each scale; tiny hops stick close, colossal kicks send you rebounding like a polite wrecking ball. Slide is your secret weapon, shaving corners and squeezing under bars you swore were impossible a second earlier. Best of all, thereâs a tiny late-jump buffer that converts âI pressed, I swearâ into âyes, we saw your courage.â Failures teach timing instead of punishing it.

đşď¸ Zones that evolve as you do
The tutorial garden is a cheerful lie with wide stones and forgiving rails. The warehouse is a geometry lesson: conveyor belts that either help or heckle depending on your mass, stackable crates that become hopscotch or high-rises. The neon city puts you on billboards, monorails, and wind tunnels between rooftops where scale dictates which alleys exist. The volcano zone is the spicy finalâshifting plates, timed geysers, and narrow lava ribs forcing clever shrink-grows on the beat. Each biome reuses ideas with new arithmetic: the same spinner that was cute at knee height becomes an event at shoulder height and a negotiation at skyscraper height.

𧊠Puzzles disguised as parkour
Youâll stand before a door with a weight sensor and grin. Do you gulp coins to bulk up and stomp it open, knowing youâll be too big to fit the service tunnel behind it? Or do you shrink, slip through an air vent, and discover a hidden line that skips an entire section? Buttons weigh outcomes. A scale platform lowers at âmedium youâ but refuses âtiny you,â inviting a breath of growth mid-landing to set it moving. A seesaw bridge asks you to arrive small, grow on the pivot so your side dips, then shrink again to sprint up the new angle. When it clicks, you feel less like a runner and more like a conductor, cueing size and speed like sections of a band.

đĽ Checkpoints that keep momentum hot
Respawns are snappy and fair. You pop back with the size you had on crossing, so each segment becomes its own tiny lab. Tinker with growth order, test a greedier coin line, and lock a cleaner split without replaying last chapterâs drama. Optional time shards hover tauntingly off-path; snatch them for leaderboard gas or ignore them for a calmer heart rate. The game respects both moods and makes switching between them effortless.

đ§ Sound you can parkour by
Growth pings rise in pitch as you balloon, shrink pads sing a cool descending trill, and coin clusters chime in little arpeggios that double as metronomes for perfect jumps. Fans wind up to a sweet spot right before theyâre strongest, spinners click once per rotation so you can jump by ear, and fragile glass tiles make a sad clink exactly one beat before they go goodbye forever. With headphones, youâll start playing the soundtrack like itâs a guide.

đ¨ Clarity with personality
Colors signal truth. Blue says âsmaller,â gold beams âgrow now,â red hums âhazard, but also opportunity if youâre brave.â Outlines thicken with speed, particle trails bloom politely and vanish fast, and accessibility toggles add symbols to color cues so every brain can parse chaos in a glance. Cosmetics lean playful: stretchy hoodies that elongate as you do, neon sneakers that leave height-mark ticks on the air, comet tails that draw your route like a mural. None of it touches hitboxes. All of it boosts swagger.

đ§ Modes for every kind of goblin
Classic Course is the heartâlearn, laugh, improve, repeat. Time Trial tightens leniency and adds ghost replays so you can race yesterdayâs you with petty delight. Puzzle Lab isolates the trickiest size switches and lets you loop them until your thumbs memorize solutions your mouth canât explain. Endless Stair is absurdist cardio: platforms generate forever while your size oscillates on a sine wave you can ride if you stop arguing with it. Daily Run drops a fresh seed with weird modifiers like âno coins, only padsâ or âshrink lasts longer, grow hits harder,â perfect for a coffee break flex.

đĄ Micro-tips youâll pretend you invented
Aim your camera where youâll land; growth follows gaze. Dash on the exit of a jump, not the entry; it multiplies distance instead of stealing control. Tap jump off fans as tiny, ride them as mid-size, avoid them as mega unless you enjoy meeting the ceiling abruptly. When a doorway looks rude, slide first, then shrink; the combo buys you centimeters that feel like miles. And if a section starts tilting your brain, run it small once to relearn rhythm, then add coins one by one until greed and control sign a peace treaty.

đ Why it belongs on your Kiz10 rotation
Because it turns a simple obby into a living toybox where movement and size negotiate every second. Because five minutes buys a new checkpoint and one glorious âI shouldnât fit but I doâ moment. Because an hour becomes a highlight reel of midair size swaps, greedy shortcuts that actually worked, and a last stretch where you shrank at the last possible frame and slid under a gate while laughing at your own audacity. Obby: Grow with every step is the rare platformer that teaches you to think with your feet and your scale at once, and the result is pure, replayable delight.
