SPECTER SNAKE
“The Classic Snake Formula, Inverted by Alchemy.”
Feed your hunger with Rubedo souls, cut through your own ghost tail to escape deadly traps, and survive the trials of the Athanor.
⥠What is Specter Snake?
Born deep within the legendary Athanor â the mystical furnace of the medieval alchemists â you awaken as an ephemeral phantom serpent trapped in the void of Nigredo.
Cursed with relentless spiritual decay, your ectoplasm is constantly evaporating. To maintain your form, you must hunt the radiant Rubedo Souls. But every soul you harvest lengthens your body, twisting the 21x21 chamber into a labyrinth of your own making...
Except here, touching your tail isn't instant Game Over. Growing longer gives you a tactical shield of amputatable ghost segments that can be sacrificed in moments of crisis!
đŽ The Spectral Rule: Surgical Amputation
Forget everything you know about traditional snake games. In Specter Snake, your body obeys the laws of spectral alchemy:
Dense, Solid Head (100% Opacity)
Your guiding focal point in ectoplasmic cyan. Smacking into perimeter salt walls or crystallized obstacles means instant death.
Translucent Ghost Tail
As your body grows, trailing segments lose density linearly until fading down to 20% opacity (80% transparency) in ethereal violet mist.
Surgical Cut (Bite Your Tail!)
Trapped in an impossible corner? Bite through your spectral tail! Your head slices through the ethereal ectoplasm, amputating trapped segments and granting a miraculous escape.
Calculated Risk & Reward
Cutting faint segments near the tip incurs minimal HP damage and drops your multiplier by only -1x. Cutting dense segments near your neck inflicts severe trauma and halves your multiplier.
Linear Opacity Gradient
Opacity(i) = 1.0 - 0.80 Ã (i / (N - 1))The head (i = 0) has 100% solidity, while the tip of the tail (i = N - 1) fades to 20% opacity. Severed segments evaporate into dark smoke over 2 seconds without collision.
Amputation Damage & Penalty
HP_Damage = round(100 Ã Opacity(i))If Opacity(i) ≤ 35% (surgical tip cut), the multiplier drops by only -1x. If Opacity(i) > 35% (deep body cut), the multiplier drops to ⌊M / 2⌋.
Purity & Integrity Bonus
Bonus = round(Max_Len à 25 à Integrity)At the end of your run, your final score receives a transmutation bonus based on maximum length achieved and the ratio of segments preserved without amputation.
đ The Trials of the Athanor (Dynamic Hazards)
The alchemical furnace reacts to your evolution through the classical stages of the Great Work (Magnum Opus):
đ Crystallized Salt Pillars
Every 10 Souls harvested, a lethal crystalline monolith materializes across the arena after a 1.5s flashing warning (up to 18 active pillars). One touch means instant petrification! Topological BFS validation guarantees no pillar ever creates dead-ends or unreachable souls.
âī¸ Scorching Solar Beams
Starting at 20 Souls harvested, concentrated beams of sunlight sweep rows (1x5) or zones (3x3) every 12 seconds. After a 2.0s amber warning, the beam ignites the grid for 2.5s, draining -10 HP per tick and evaporating any trailing tail segments caught in its path.
đ Maximum Multiplier (8x)
Each Rubedo Soul restores +10 HP and awards 10 × Multiplier points. Every 5 consecutive souls collected without amputation increases your multiplier by +1x up to 8x, awakening the golden Athanode Sigil at the heart of the furnace!
