“Hold nine coins and you're fine. Reach for the tenth, and the pyramid drags you to the torture room.”
◆ THE GREED LAW · THE FLOAT · THE BOMB CHAIN ◆

Tecmo's 1986/87 NES sequel to the arcade Bomb Jack: a caped hero floats up a sixteen-level pyramid to rescue a kidnapped royal family from a demon — and the whole game is built around one severe rule, a punishment for greed. Catalogued into UD0 as a game-world, in 8-bit, rendered from the game rather than invented — with its famous fan myths corrected.

The Four Natures

each emergent comes by one of four natures — the cast, the lift & lightness, the systems & treasure, and the law & the demon

natural
the cast — Jack and the royal family he climbs to save, and the Mighty brothers who tried first and failed; the people of the rescue
ethereal
the lift & the lightness — the cape-float, the Sphinx's hidden ways, and the impossibly sunny soundtrack over a brutal game
electrical
the systems & the treasure — the bombs and their chains, the Mighty Coins and their three suits, the Palace rooms and the warp; the machinery of play
spiritual
the law & the demon — the anti-greed rule, the torture room, the pyramid as a moral test, and Belzebut waiting at the top

The Arc

the overall throughline, then the three beats: the kidnapping → into the pyramid → the temptation & the demon

THE OVERALL ARCThe demon Belzebut has kidnapped the royal family of the Land of Pamera — the King, the Queen, and the Princess — and carried them into a pyramid. The Mighty brothers went in first to rescue them, and failed. So Jack — who floats by feathering his cape — goes in alone, climbing sixteen levels of action zones and single-screen Royal Palace rooms, collecting bombs in their lit order, cycling power suits, and resisting the one temptation the whole game is built around: taking too much. Hoard a tenth coin, and the pyramid will drag him to a torture room.
I · the kidnapping
Belzebut takes the Pameras

The demon Belzebut seizes the royal family of Pamera and drags them into the pyramid. The Mighty brothers attempt the rescue first — and fail, leaving the throne empty and the family lost somewhere above. Only Jack is left to try.

II · into the pyramid
float, bombs, suits

Jack enters: sixteen levels, each a scrolling action zone followed by a single-screen Royal Palace room — the old arcade Bomb Jack at its heart. He floats by feathering his cape, grabs bombs in their lit-fuse order for chaining bonuses, and spends Mighty Coins to cycle three suits that open the treasure chests.

III · the temptation & the demon
resist greed, reach Belzebut

The pyramid is a moral test. Every chest and coin tempts Jack toward the tenth — and the torture room. Holding his greed, climbing through one-hit-kill danger under a relentlessly cheerful tune, he reaches the top, defeats Belzebut, and frees the royal family of Pamera.

The Greed

this game's deep-dive — the famous anti-greed mechanic (the tenth coin, the torture room, exactly), plus the cape-float, the bomb chains, the three suits, and the cheerful-cruel reputation

The Greed Law
the torture room, exactly

The game's defining, famous mechanic — and the centerpiece here. Jack can safely hold up to NINE Mighty Coins. Pick up a TENTH (more than nine), OR let the on-screen timer exceed 99 seconds (you push it there by greedily over-drinking Mighty Drinks, +10s each), and he is instantly teleported to a sealed Torture Room. It is NOT a soft-lock and NOT instant death (both common fan myths): to escape, Jack must jump off the floor 50 times — a counter ticks down from 50 — while four randomly-chosen enemies hunt him and one touch still kills. Escape, and he loses ALL his coins, the timer resets, and he's dumped back at the start of the stage. A humiliating 'do it again with nothing,' for the crime of taking too much.

The Float
feather the cape

Jack's signature move: he doesn't just jump, he FLOATS. Feathering (tapping) the jump button flaps his cape and slows his descent into a hover; pressing it again mid-rise halts his ascent, and holding up or down tunes the arc higher or lower. Mastering the gentle, deliberate float — over spikes, between enemies, onto a single safe tile — is the whole skill of the game.

The Bombs & the Chain
grab the lit fuse

Inherited from the 1984 arcade Bomb Jack: a Palace room is full of bombs, and at any moment one bomb's fuse is lit. Grab the lit one and the next lights in turn — chaining the sequence escalates the bonus. The expert flourish: save the originally-lit bomb for last (the 24th) and Jack warps straight to the next Palace room.

The Three Suits
Blue, Orange, Green — not invincibility

There is no invincible 'Mighty Mode' (another myth). Spending Mighty Coins cycles Jack through three colored power suits: BLUE lets him open locked chests by jumping on them; ORANGE opens any chest by touching it from the side; GREEN turns every on-screen enemy into a collectable coin for about five seconds — which is, of course, the fastest way to tempt yourself straight past nine and into the torture room.

Cheerful & Brutal
the sunny soundtrack over a cruel game

The lasting impression: Mighty Bomb Jack is cryptic, obtuse, and brutally hard — one hit kills, guidance is nil, and the greed law punishes the natural instinct to grab everything. And yet the soundtrack (Tsukasa Masuko and Michiharu Hasuya) is sunny, bouncy, and irresistibly cheerful — a bright little march wrapped around a punishing pyramid. Modern re-reviews skew mixed-to-negative; the cult affection survives anyway, largely on that contrast.

Real or Fluff

the verdict — correcting the fan myths (no inescapable soft-lock, no invincible 'Mighty Mode,' no canonical 'Pyramid of Ra,' threshold is ten not six) and confirming what's real

Hoarding sends you to an INESCAPABLE torture roomthe Torture Room is real but escapable — jump 50 times while four enemies hunt you; the real penalty is losing all your coins and restarting the stage
MYTH
The greed threshold is six coinsit's the TENTH coin — you can safely hold nine; the 10th (more than nine) triggers it, as does letting the timer exceed 99 seconds
FALSE
There's an invincible 'Mighty Mode'Mighty Coins cycle three chest-opening suits (Blue / Orange / Green), not invincibility
FALSE
It's set in the 'Pyramid of Ra'it's a pyramid with Egyptian / Ra / Sphinx motifs, but 'Pyramid of Ra' as the canonical level name isn't well-attested — say 'a pyramid'
UNVERIFIED
It punishes you for playing naturallythe whole design penalizes the collect-'em-up instinct to grab everything — greed, the most natural impulse, is the trap
TRUE
It's brutally hard — one hit killsone touch is death, the game is cryptic and obtuse, and modern re-reviews skew mixed-to-negative; it keeps a cult following
REAL
The music is gloomy to match the crueltythe opposite — the soundtrack (Masuko & Hasuya) is famously sunny and cheerful, an odd, charming contrast to the punishment
FALSE
It's the sequel to the 1984 arcade Bomb JackTecmo's follow-up; the single-screen Royal Palace rooms are the original arcade game preserved inside the sequel
REAL
Bottom line: almost everything 'everyone knows' about Mighty Bomb Jack is a little wrong. The torture room is real but escapable (fifty jumps, four hunters, lose all your coins, start over), not a permanent soft-lock; the trigger is the tenth coin, not the sixth; there's no invincible 'Mighty Mode,' just three colored suits; and it's 'a pyramid,' not a canonically-named 'Pyramid of Ra.' What's completely true is the heart of it: this is a game whose central rule is a punishment for greed — it tempts you with coins and chests and an enemies-into-coins suit, and then drags you to the torture room the moment you reach for one too many. It is genuinely brutal and obtuse, and modern eyes mostly find it broken. But that one severe idea — a platformer that polices your appetite — set under the sunniest music on the system, is a strange, memorable little piece of design. The pyramid is a morality test in 8 bits.

The Message

what AVAN reads as the game's actual thesis, under the sunny soundtrack: enough is enough

Mighty Bomb Jack is a cheerful game about not being greedy. It looks like a sunny Egyptian platformer — bright palette, bouncy march, a little hero who floats up a pyramid by flapping his cape — and its single defining rule is a punishment for the most natural instinct any collect-'em-up ever trained into you: grab everything. Hold nine coins and you're fine. Reach for the tenth, or linger too long drinking for time, and the pyramid yanks you into a torture room and makes you jump fifty times, hunted, to crawl back out with nothing. It is obtuse and brutally hard and was never really beloved — but that idea, a game built to police your appetite, is a genuinely odd little piece of design philosophy: the pyramid as a morality test, the demon at the top almost beside the point next to the demon of wanting more. Take what you need, leave the tenth coin, and the cheerful music carries you up. Reach too far, and it carries you right back to the bottom. The whole game is one small, sincere sermon: enough is enough.

“Hold nine, leave the tenth. The sunniest music on the NES, wrapped around a law against greed — the pyramid is a morality test, and the demon of wanting more is the real boss. Enough is enough.”— AVAN's read

whereTriggered anywhere the tenth coin is taken; served in a sealed torture chamber.

whereScattered through the levels as a tempting clock-extender.
whyBecause the game punishes hoarding of every kind, and time is just another thing you can take too much of.

Rendered, not invented. Mighty Bomb Jack is a game, not a cast — so this world carries no .shadow (no real-world Users behind the figures). Every emergent here is distilled directly from the game's verified characters and mechanics, with the famous fan myths corrected in Real-or-Fluff. The mechanics are the systems themselves, made into characters: the greed law, the float, the bomb chain, the three suits, the Palace room, the Mighty Drink, the pyramid, and the sunny soundtrack.
