iPhone v2.0.6 · Now Available

Made for iPhone Duo, folded or open

Gaboon Viper 2.0.6 is free on the App Store now. When iPhone Duo is folded, the play area extends below the front camera and the A/B buttons have more room. Open it, and the controls sit lower for an easier grip. The leaderboard keeps its familiar layout, and the standard iPhone layout is unchanged.

Mechanics Deep Dive

Every bite is a delayed bet

Unlike classic snake games where eating instantly lengthens the body, growth in Gaboon Viper is a delayed, physical digestive process with real risks and weight.

🥚 Delayed Digestion

Swallowed eggs form lumps inside the body, moving backward with each step, and only add length once fully metabolized.

💥 Stomach Capacity (BURST)

Your GUT meter tracks load in Green (safe) → Yellow (caution) → Red (critical). Overeating beyond 100% causes an instant BURST game over!

⌛ Starvation & Atrophy

Eating resets the 6-second hunger timer. If you starve past 6s, your body shrinks 1px every 2 seconds until you wither away (TOO EMPTY).

🏆 Three Game Modes

Includes Standard Mode across 10 worlds (100 stages), Map Mode for stage practice, and the new 5-minute Time Attack rush.

Tactical Items

Master items to survive and triumph

Six randomized tactical pickups appear across the field, offering strategic relief and game-changing bonuses.

🧪 Laxative / Poison Emergency Cleanse

Instantly purges all undigested lumps and shrinks length by 3px to avoid bursting. Crucially, shrinking never penalizes your historical MAX score multiplier!

⛸️ Roller Skates Speed Surge

Grants an 18% movement speed boost and +50 points. Perfect for weaving through tight corridors and sharp turns at high velocity.

🩴 Wooden Clog Steady Brake

The opposite of skates: slows you down, and one clog cancels out one pair of skates. Resets when you clear a stage, +50 points. Hit the brakes when you're stuffed and need steadier turns!

💣 Cannonball Bomb Deadly Hazard

Randomly rolling lethal mines that detonate on contact. However, if struck while invulnerable (Diamond), you defuse it for an extra +100 point bounty!

💎 Diamond Invincibility

Rare tactical gemstone (7.5% spawn) granting +200 points and 8 seconds of rainbow invincibility, enabling you to smash through bombs and hazards safely.

⚗️ Enzyme Metabolism Overdrive

Awards +50 points and triples digestion speed for 5 seconds, rapidly turning stomach lumps into length and clearing gut space in a flash.

☠️ Seven Death Conditions Full Analysis

The game strictly monitors 7 causes of death: BURST (overeating), WALL (boundary crash), BITE (self collision), TOO EMPTY (starvation), BOMB (mine blast), HAZARD (obstacles), and RIVAL (touching the rival snake).

Controls

Portrait and landscape

Use the on-screen D-pad and A/B buttons. Standard mode progresses stage by stage; Map Mode lets you practice specific worlds, and Time Attack offers a 5-minute rush.
