ГРИБ: Versus is a browser runner: a mushroom stomps plumbers to a shuffled 400-track soundtrack and meets a random boss every 7 levels. The mushroom is a nod to the Oxxxymiron vs Слава КПСС Versus battle.
- Tap / Space -- jump (tap again mid-air for double jump)
- Land ON enemies to stomp them
- Collect bonuses: 🍄 big mushroom (survives one hit), 🚀 jetpack, 🦠 spores, 🌀 slow-mo (then a short speed-up), 🧲 magnet, 💰 loot, 🎰 slot machine, 🎞 noir (one zone in black and white, bonuses burn, the big mushroom stays), and six more that open up through the ladder: ⭐ star (5 s: nothing hurts, faster, touch kills; pits still kill), 🟢 1UP (a second life in stock; the first elite killed in a run drops one), 🫧 bubble (held: saves you from the next pit), ⚡ zap (6 s: enemies smaller and half speed, the boss freezes for 2.5 s and its attacks vanish), 🎤 punch (instantly removes up to three enemies ahead, or hits a boss once), 👻 ghost (4 s: everything passes through you, no stomps). When a run goes badly (small mushroom, no stomp for 10 s) helpers drop twice as often and loot and slot machines half as often
- Hedgehogs can't be stomped; wrench throwers and diving pigeons can
- The first seven levels are gentler: a big mushroom always waits at the start of levels 3, 6 and 9 (except during the black-and-white zone), speed grows more slowly, and hoppers and wrench throwers only appear after level 7
- Bosses: every 7th level brings one of seven, the king always last in the round of seven; repeats get numbered II, III. Each one goes down a different way:
- ГЛАВНЫЙ САНТЕХНИК (4): stomp him while he charges
- ГОЛУБИНЫЙ КОРОЛЬ (3): out of reach; his eggs bounce toward you (stay under a high arc, jump a low touch-down) and the golden one, stomped, flies back at him
- ДУТАЯ ФИГУРА (3): the ball itself bounces at you; its shadow shows the next landing and turns red when it will land on you — head-butt it from below in a jump
- СТЕКЛЯННЫЙ ПЕТУХ (3): don't hit it; he shows a song as notes, then pecks it on a beat — clear the whole song untouched and the glass cracks
- ПОДЗЕМНЫЙ ЧЕРВЬ (4): be in the air when each mound reaches you, then stomp the real head, not the thorny ones
- ЛЕТАЮЩАЯ ТАРЕЛКА (3): out of reach; discs come one at a time, low ones you jump and high ones you ignore on the ground; a mark under you blinks three times and freezes with a loud beep: jump when it freezes (or a little earlier) to be airborne for the flash; then stomp the golden disc, it throws you onto the saucer
- ЦАРЬ ГРИБОВ (5): stomp him while he squats and crawls; from the third stomp he wears armour until you stomp a soldier he summons
- Mini-bosses are elites now, no arenas: from level 4 on one may walk a level's ordinary platforms (at most one per level, only on platforms at least 300 px wide, never over a pipe, never on a boss level; in БАТТЛ there is one on every level from the first). Kinds: ОКСИ, ШОК, ГНОЙНЫЙ, ТАНЦОР or РИКИ Ф. Two stomps: 500 for the first, which shrinks it and throws it ahead, 1500 for the kill; the first elite killed in a run drops a 1UP. It stands on its platform until the mushroom is 620 px away, then chases: keeps a distance ahead, crouches with a "!" for 0.45 s and charges (closing at 210 px/s, 260 from level 8). Dodge a charge and it drops off the left edge, comes back and leaps over you, and after a third failed charge it gives up and runs away. Its body only hurts while it is on the ground in the chase or the charge
- Z key -- spin the slot machine (two charges at most, a third pickup gives +300; outcomes now include a star, a 1UP, 8 s of spores and turning every enemy on screen into pigeons)
- New players start every normal run with a second life (🟢) until they beat a first mini-boss or boss
- Sparring: every boss and mini-boss you have met has a Спарринг button in the Боссы tab: a practice fight that scores nothing and changes no goals
- 15 zones on a loop with procedural backgrounds, 7 enemy types, each with its own temper: speed, lunges, dips, bursts
- A random boss every 7 levels, seven kinds, each with its own movement and hit window
- Menu with nickname, music toggle, bonus and level info, online top-10
- Share card for Telegram and other apps (the game link is copied for the next message)
- Mobile-friendly: touch controls, and on screens narrower than 640 px the world is drawn zoomed out, so a phone sees about as far ahead as a small desktop window
- Hip-hop quotes as kill banners
The «Забег дня» button starts the run of the day (Moscow date): the same platforms, enemies, bonuses, boss, mini-boss and track order for everyone that day. Secret nicknames play as plain mushrooms and start perks are off, so the daily top (keys day:YYYY-MM-DD:NAME) compares like with like. The server takes scores for a day only while that Moscow day is today or yesterday. Boss attacks stay random. Playing on consecutive days builds a streak shown on the button and the share card.
A 15-step ladder opens up over successive runs: the first steps land in the first session (a x3 combo and reaching level 3) and hand out the six new items one by one (🫧 bubble, 🟢 extra life, ⚡ zap, ⭐ star, 👻 ghost, 🎤 punch). The old eight pickups stay available to everyone; in a daily run every item can drop. Later steps unlock start perks (big mushroom, casino charge, magnet, spores, a second life), the БАТТЛ and ЛЕГЕНДА modes, and the gold hat.
The Секреты tab opens at level 3: each finished step reveals one more secret nickname; unrevealed ones show only a riddle. Typing a nickname by hand works regardless. The Коллекция tab (was Боссы) lists bosses and mini-bosses met and beaten, the 14 items collected, the secret rooms found and the heroes played, with one total counter on the chip; every met boss and mini-boss keeps its Спарринг chip (a practice fight on a plain mushroom that posts nothing to the top, the counter or the goals).
Pipes and secret rooms (v43): about 3% of long platforms from level 2 (at most one per three levels, none on arenas or in sparring; seeded per platform, so the daily run has the same pipes for everyone) carry a green pipe. Landing on top of it puts the run aside and opens a room: ПОДВАЛ (10 s, twenty coins), КАЗИНО (three free spins) or ЧЁРНЫЙ ХОД (4 s, comes out up to two levels ahead, never past a pending boss or mini-boss). Finding all three doubles the pipe chance.
Progress lives in the browser. A player who has never beaten a mini-boss or a boss gets one extra life (🟢) in normal runs.
The game plays 400 15-second clips that live in their own repo, mushroom-clips, so a game release does not re-upload 96 MB. Their titles are kept in its manifest.json lightly obfuscated (XOR plus base64), so no artist or track name sits in the repo as plain text. The tracklist is Russian hip-hop only: the first 200 come from the owner's own library (favourites, Kunteynir, Бабангида, Паша Техник), the rest are the channel's 2023-2026 picks — year-end top lists, release reviews and profiles from @psyterrormagazine — downloaded and cut per track. Every run shuffles the pool, so each zone gets a different track and its banner shows that track's name. A clip is downloaded when its zone comes up, with the next one fetched ahead, so a visit costs a few hundred kilobytes per zone and not the whole 96 MB pool. Boss fights also get a random track. The full pool list is a hidden menu tab that unlocks once your nickname reaches the top 5 of the leaderboard. tools/cut-clips.py cuts the clips from a private music/ folder that stays out of git into a mushroom-clips checkout next to this repo (or CLIPS_DIR), and the audio files themselves carry no tags.
Scores live in one place: a small Go + SQLite server (server/) that keeps the best score per nickname, with names in caps. The public API can only read and add. Deleting goes through an admin port that only the server itself can reach:
ssh <vps> grib-lb ls # every row
ssh <vps> grib-lb rm NAME # NAME on both boards; or v2:NAME / v2s:NAME / day:YYYY-MM-DD:NAME for one
ssh <vps> grib-lb stats [DAYS] # anonymous run counter: new and returning players, shares, where runs end
The run counter stores only a UTC day, an event name and a count: run start (new browser, back on another day, again today), run end (level, cause: pit, enemy or the boss kind, and whether the screen was narrow) and share clicks. Each browser also sends a week bucket on its first start of a day (week:w0..week:w12, whole weeks since that browser's first visit), so the counter shows week-to-week return. No ids, nicknames or addresses.
Scores that fail to send wait in the browser and go out on the next visit or when the network returns. With no network the menu shows the last board this browser saw.
The API is public HTTPS on the server's own address, not a tailnet name: a browser on a device inside the tailnet treats a tailnet address as local network and blocks it from a public page.
No build step. index.html holds the markup and loads style.css and js/*.js in a fixed order; the scripts share one global scope. Bosses live in js/bosses.js and js/boss-draw.js, mini-bosses in js/minis.js, zones in js/zones.js.
Current build: v47 (shown in the bottom-right corner of the game).
The first version took half a day with Claude Fable. Version 2 (zones, bonuses, enemies, audio, graphics, menu and bosses) grew over several sessions with Claude Opus and Sonnet. Plain HTML and JavaScript: no build step, no libraries.
