FNF V.S Spong (Full Week) — KADE Engine Browser Port: Spong's surreal full week lands on KADE — three songs, real difficulty curve
FNF V.S Spong (Full Week) is a Kade Engine port of the cult-classic V.S Spong mod, rebuilt by Axmed to run as a browser-playable HTML5 build with the full week's songlist intact. Spong himself is a deliberately bizarre, surreal opponent — equal parts creepy and absurd — and the mod leans into that energy with chunky visual gags, distorted sound design, and a chart difficulty curve that ramps hard once you get past the opening track. The full-week format means you're getting three full songs plus any associated bonus content the mod ships, making this a much meatier package than the typical single-song FNF drop. Because it ships on the KADE Engine, the chart feedback is meaningfully better than vanilla FNF: combo counters, accuracy grades, opponent health drain on miss, and charts designed around the engine's stricter timing windows. The week format gives you a real arc — easy opener, mid-tempo challenge track, hard closer — so you can sit down and actually progress through the mod rather than just grinding one song. For FNF players who want a tight, self-contained weekend mod with a strong identity and actual charting depth, V.S Spong is one of the more distinctive picks in the current mod scene. It's also a great litmus test for KADE newcomers since the difficulty curve is well-paced rather than front-loaded.

Did You Know?
V.S Spong is part of the wave of mid-2020s FNF mods that leaned into weird, surreal character design rather than the more typical anime-style opponent art — the mod's whole aesthetic is built around Spong's deliberately unsettling, blocky visual identity. Axmed's KADE Engine browser port preserves that vibe while making it accessible to anyone with a browser, which is part of why the mod has stuck around in the FNF community years after its initial release. The full-week format is also rarer than you'd think among KADE ports, which usually ship one or two songs at a time.
Key Features
Why You'll Love It
If you're a fan of pick-up-and-play games that respect your time, FNF V.S Spong (Full Week) is tailor-made for you. It's perfect for those moments when you want quick, satisfying fun without a steep learning curve — offering a refreshing blend of simplicity and addictive gameplay. The easy-to-learn controls and instant action ensure you're always just one click away from a great time.
How to Play FNF V.S Spong (Full Week)
Open the embed in your browser and let the game load. From the title screen, pick a song from the Freeplay menu or step through the week in story mode. Hit the arrow keys (or WASD if you've rebound them in the options) in time with the notes as they reach the receptor at the top of the playfield. The goal is to outperform Spong — land clean hits to drain his health bar while keeping your combo alive across the full track. Make sure you're on a physical keyboard — mouse and touch aren't supported for the actual note hitting. If you're new to KADE, start at 0.75x speed in Practice mode for the opener track before tackling the closing track at full speed; KADE charts hit noticeably harder than vanilla FNF and the difficulty jump between Spong's songs is real.
Disclaimer: These are the standard controls for this type of game on PC Browser with Keyboard/Mouse. The actual controls may be slightly different.
| Action / Purpose | Key(s) / Gesture |
|---|---|
| Arrow keys or WASD | hit notes. Enter to confirm |
| Escape | pause. |
Tips & Tricks
Start in Practice at 0.75x speed — KADE charts hit faster than vanilla FNF and Spong's opener is friendlier than its follow-ups.
Don't panic-tap through Spong's mid-song rolls. The chart layers 16th notes over weird vocal samples that punish panic input; slow down and read two arrows ahead.
Watch Spong's health bar, not just your combo. KADE punishes the opponent hard on every miss, so a partial clear can still win you the round.
Listen for the vocal kick anchors in each track — Spong's songs have strong downbeat transients the chart leans on. Locking onto those keeps your combo alive through the busier runs.
