Mini Switcher

The blob walks on its own. That is the first thing to understand about Mini Switcher, and everything else follows from it. There is no left, no right, no jump and no brake. A pink cube of eight pixels sets off across the screen at a constant 40 pixels a second, turns around when it meets a wall, and keeps going. You have exactly one button, and all it does is turn gravity upside down.

Press it and the blob falls up. Press again on the ceiling and it falls back down. Between those two presses the outcome is already decided — the walk speed is fixed, the hazards run on written-down timers, and the level fits on one screen with nothing hidden off-camera. The game never asks whether your fingers are quick. It asks whether you can read a room and pick a moment.

There is a catch, and it is the whole character of the game: the flip only works while the blob is standing on something. Press in mid-air and nothing happens. The input survives four frames — about 67 milliseconds — and if you have not landed by then it is thrown away without a sound.

It was built by KezArts, which gives away HTML5 games at kezarts.com and used to trade as NoaDev, which is why the earliest published version, dated 2 April 2019 on Armor Games, carries the old name. The build here is the one the title screen labels 2.0, distributed on 14 September 2020. It scores 76 out of 100 from 147 votes on Armor Games across some 28,600 plays, and 6.4 out of 10 from 264 votes on GamePix — the same modest verdict twice. There is a mechanical explanation for that further down.

One button, two states: the design principle underneath

Most platformers spend their button on an action. You press, the character jumps, and by the time you land the world is exactly as it was — gravity still points down. The press is a transient impulse and its effects expire.

Mini Switcher spends its button on a state. Press, and gravity inverts and stays inverted until you press again. You are not metering the height of a jump; you are choosing which of the level's two floors you belong to, and living with the choice until you change it.

Strip away the steering as well, as this game does, and the design becomes almost mathematical. The blob's horizontal position over time is fully determined; the hazards are on fixed cycles. The only free variable left is the timestamp of each press, which is why the levels feel like puzzles with a stopwatch attached rather than tests of dexterity.

This is a real lineage, not a coincidence. The best-known game built on it is VVVVVV, released by Terry Cavanagh in 2010, whose protagonist cannot jump at all and instead reverses gravity — and, exactly like this game, can only do it while standing on solid ground. Before that, Metal Storm (Tamtex and Irem, NES, 1991) built whole stages around gravity reversal, though bolted onto a conventional run-and-gun.

Mini Switcher goes further than either. VVVVVV still lets you walk left and right. Here you do not even get that.

Is it fair? Three reasons yes, three reasons no

The grounded-only rule is what makes the mechanic legible, and also what makes players call the controls unresponsive. Both are true.

What the game does honestly:

• Complete information. The playfield is 176 by 136 pixels — 22 by 17 tiles of 8 pixels — and the camera is bolted down. No hazard ever arrives from off-screen.
• Deterministic, telegraphed cycles. Nothing is random. Cannons fire every 1.5 to 5 seconds, butterflies patrol one tile over six seconds, spears run their 4.5 second loop. The author even hand-wrote the phase offsets — in level 15 a row of nine ceiling spears has start delays stepping up by exactly 20 frames each, so they fire in sequence like a wave rolling down the corridor.
• Zero wind-up. The frame you press is the frame gravity changes.

What feels unfair:

• It eats your early presses. Outside those four frames there is no feedback at all — no buffered flip, no click, nothing. A press made half a second before landing simply never existed.
• No forgiveness at edges. Games in this genre often grant a few frames of grace after you leave a platform. This one grants none.
• The slow start of every fall, which makes gaps hard to judge until you have felt a few.

That second group is very likely why this sits at 76 out of 100 on Armor Games — the lowest-rated of the studio's 29 games there, in a catalogue where Mini Dash scores 92, Mini Jumps 93, Mini Sticky 94 and Mirror Wizard 96. The levels are not the problem. The four-frame window is.

The thirty levels, and the order the hazards arrive in

The campaign is paced with unusual discipline for a free browser game. Levels 1 and 2 have no hazards at all — the first is the only one that shows the tutorial text, and both exist purely to teach you what a flip feels like. After that a new hazard arrives every two or three levels:

Hazard	First appears	Behaviour
Spikes	Level 3	Static, on floors and walls. 59 in the game
Gum	Level 5	Creeps along a surface at 0.6 pixels per frame
Cannons	Level 8	Four variants — floor or ceiling, firing across or up. Reload 1.5 to 5 seconds
Springs	Level 11	Launch you at 2 to 6 pixels per frame after a 1 to 3 second wait
Spears	Level 13	Retract and extend on the 4.5 second loop. The most common hazard, 79 of them
Butterflies	Level 15	Drift one tile back and forth over six seconds

That is 217 hazards across thirty screens, and the density climbs unevenly. Level 10 has just two cannons and the most solid terrain in the game, while level 23 is the crunch point with sixteen hazards on one screen: four butterflies, eleven spears and a spike.

The whole thing was authored in Tiled 1.3.1 on an 8-pixel grid, which is why the levels read so cleanly. Every hazard sits on a tile boundary, so once you can judge one gap you can judge all of them.

Speedrun mode, and why it is the better way to play

The main menu offers SPEEDRUN alongside START, open from the start rather than locked behind the campaign. It drops you at level 1 and runs all thirty back to back against a clock counting milliseconds. The record only writes if you finish level 30, then sits on the menu as BEST for 60 days.

Two things make it the mode worth your time. The levels are short and completely deterministic, so a run is a memory test with a scoreboard. And, unusually, the time-triggered adverts are switched off during a speedrun: in the normal campaign an interstitial can appear about 30 seconds into your first session and then roughly every 110 seconds between levels, but in speedrun mode that timer never fires.

One inconsistency worth flagging — the Armor Games listing says speedrun unlocks only after you beat every level. In the build served here it is available immediately.

Playing Mini Switcher unblocked at school

If you found this game on a school Chromebook, it is no accident that it worked. Mini Switcher is one HTML5 page with no plugin, no installer, no login and no download. It renders its 176 by 136 pixel canvas through WebGL and falls back to plain Canvas 2D where WebGL is unavailable, which covers almost every locked-down managed device. The entire game, level data included, is a few hundred kilobytes.

Progress is stored in your browser rather than an account, with a 60-day expiry, so a shared school machine remembers your cleared levels for about two months and then quietly forgets. Clear the browser data or switch computer and you start again at level 1.

It also plays properly on a phone. The touch build swaps the keyboard prompt for "TOUCH TO SWITCH THE GRAVITY", and a tap anywhere does the job — fitting, for a game whose entire control scheme is one binary input.

More games by KezArts

Mini Switcher belongs to a long series of tiny, sharply-scoped games sharing one engine — shared so thoroughly that this bundle still carries the unused tutorial screens for its siblings' jump and block-switching mechanics, which never appear here.

Three are on this site. Mini Steps is the closest relative: the same blob and pixel grid, but a puzzle about moving in small increments to collect every coin. Mini Swim takes the blob underwater and keeps the speedrun mode. Slime Knight swaps it for a small knight with a sword and an ancient castle.

If it is the one-button design you came for rather than the studio, ZigZag Snow Mountain is the closest match here — a skier descends diagonally and every click reverses direction, the same "single input, two states" trick applied sideways. Jumper jam is another single-input climb. Or browse the whole arcade category.

1. Pick a level. START opens a grid of thirty numbered buttons across two pages. Only level 1 is open on a fresh save; each one you clear unlocks the next and turns purple.
2. Watch before you press. The camera never moves, so every spike, spear, cannon and butterfly is on screen from the first frame, all running on fixed loops.
3. Flip with X, Space, left click or a tap. The blob keeps walking; only its idea of "down" changes. Chain flips to climb past obstacles or drop through a gap.
4. Reach the flag. Touching a hazard kills you, and so does falling off the bottom of the screen. There are no lives — the level simply restarts.
5. Press R the moment a run is dead, rather than watching it play out.

Four things the game never tells you:

• Every flip starts from a standstill. Gravity accelerates the blob by 0.1 pixels per frame, capped at 3. Reaching top speed takes 30 frames — half a second, and 46 pixels of travel — so in most gaps the blob never gets there. Aim for where it will be, not where it is.
• Holding the button does nothing. The four-frame window counts from the press, not the release, so a held button expires exactly like a tapped one. Every flip needs a fresh press.
• Spears run a 4.5 second loop — three seconds retracted, one and a half extended. Count one cycle before you commit; the next is identical.
• Levels 1 and 2 contain no hazards whatsoever. If you are dying there, it is the walking catching you out, not the level.
