Tiles & Materials

The castles are built using various materials, each with unique physics properties and hitpoints.

Index	Icon	Material	Description	Recommended Ammo
1		Wood	The weakest structural material. Easily broken by any projectile, making it an excellent weak point to target. Flammable.	Fireball (Starts fires)
2		Stone	A sturdy material with high mass. Resistant to light impacts but will crumble under heavy bombardment.	Boulder (Pierces through)
3		Glass	Very brittle but slippery. Shatters easily into pieces upon impact.	Splitter (Wide coverage)
4		Sand	Heavy and dense. Doesn't shatter like glass or wood, but dampens impacts and adds massive weight to structures.	IceBomb (Freezes to glass)
5		Water	Flows naturally and puts out fires. Can be displaced by explosions.	IceBomb (Freezes to glass)
6		Fire	Ignites flammable materials like wood, oil, and gunpowder. Spreads quickly and turns into smoke.	Tornado (Blows it away)
7		Smoke	Rises from fires and dissipates over time. Harmless but obscures vision.	Tornado (Clears vision)
8		Debris	Broken remnants of destroyed structures. Falls like sand and eventually fades away.	Tornado (Scatters it)
9		Gunpowder	Highly explosive powder. Igniting it causes massive chain reactions and huge explosions.	Fireball (Ignites)
10		Oil	Highly flammable liquid. Burns intensely and spreads fire rapidly across surfaces.	Fireball (Ignites)
11		Acid	Corrosive liquid that slowly dissolves wood, stone, sand, and metal on contact.	Tornado (Scatters safely)
12		Metal	Extremely durable and heavy. Highly resistant to physical impacts but can be melted by lava.	Lightning / Nuke
13		Lava	Viscous, incredibly hot liquid. Melts metal, glass, and ignites all flammable materials on contact.	IceBomb (Cools it)
14		Plant (Vine)	Static tile that slowly grows and spreads into empty spaces if touching Water or Dirt. Flammable.	Fireball (Burns rapidly)
15		Ice	Slippery static solid. Melts into Water when exposed to Fire or Lava.	Fireball (Melts it)
16		Snow	Falling powder. Melts into Water when exposed to heat.	Fireball (Melts it)
17		Mud	Heavy falling sludge. Over time, it dries out and hardens into Dirt.	None
18		Dirt	Basic falling solid. Touching dirt drastically speeds up the growth of Plants.	None
19		Obsidian	Extremely hard static solid. Created when Water touches Lava.	Boulder (Takes multiple hits)
20		Sponge	Static material that slowly absorbs adjacent Water cells.	Fireball (Burns rapidly)
21		Wax	Static flammable solid. Melts into Liquid Wax when exposed to heat.	Fireball (Melts/Burns)
22		Liquid Wax	Viscous liquid that solidifies back into Wax over time.	None
23		Coal	Hard static solid. Highly flammable and burns very slowly over a long time.	Fireball (Ignites)
24		Steam	Rising gas. Eventually condenses back into Water over time.	None
25		Natural Gas	Rising gas. Highly explosive when ignited by a spark or fire.	Fireball (Massive Explosion)
26		Oxygen	Rising gas. Makes adjacent fires burn longer and spread more violently.	Fireball (Boosts fire)
27		Rubber	Extremely bouncy material. Projectiles will bounce off rubber surfaces rapidly without dealing damage!	IceBomb (Freezes it)
28		Slime	Sticky green liquid. Falls downwards but occasionally clings to walls and moves sideways.	Tornado
29		Poison	Toxic purple liquid. Instantly kills any Plant cells it touches.	Tornado
30		Liquid Nitrogen	Extremely cold liquid that freezes Water into Ice, and shatters organic matter like Plants or Slime on contact. Evaporates into Smoke.	Fireball
31		Tar	Very sticky, heavy black sludge. Highly flammable and burns slowly.	Fireball
32		Toxic Gas	Rising green gas. Slowly dissipates over time.	Tornado
33		C4	Static grey explosive block. Explodes instantly and violently if touched by Fire or explosions.	Fireball (Ignites)
34		Battery	Static electrical energy block. (Coming Soon: Electrifies water and metal!)	Boulder
35		Crystal	Sturdy static transparent block. (Coming Soon: Refracts lasers!)	Boulder
36		Mercury	Heavy liquid metal. Falls normally but conducts electricity.	Tornado
37		Rust	Static corrosive material. Slowly spreads to adjacent Metal cells, weakening them until they crumble into Debris.	Splitter
38		Thermite	Falling powder. When ignited by fire, burns incredibly hot.	Fireball
39		Anti-Gravity Sand	Pink powder that ignores gravity and falls UP towards the sky.	None
40		Portal	Static magical rift. Any falling object that enters the top of the portal is instantly teleported to a random location in the sky!	None
41		Replicator	Static sci-fi machine. Continuously duplicates whatever cell is directly above it and pushes it out below.	Boulder
42		AntiMatter	Extremely dense static void block. Instantly annihilates (deletes) any non-empty cell it touches! Very dangerous.	Nuke
43		Nanobots	Falling swarm of microscopic robots. Slowly consumes all organic and stone materials, converting them into more Nanobots. Ignores Metal.	Fireball
44		Forcefield	Indestructible sci-fi energy barrier. Blocks all physical objects.	None
45		Conveyor	Static mechanical belt. Continuously pushes any object resting on top of it to the right.	Boulder
46		Black Hole Sand	Extremely dense powder. (Coming Soon: Pulls nearby objects towards it!)	Nuke
47		Radioactive	Glowing green static material. Randomly mutates nearby cells (e.g. Water becomes Poison, Sand becomes Glass, Plant becomes Slime).	Splitter
48		Virus	Hyper-aggressive bio-weapon. Rapidly infects and converts all organic material (Plants, Wood, Slime, Mud) into more Virus until it dies out.	Fireball
49		Ground	Indestructible bedrock foundation of the level. Cannot be destroyed by any means.	None

Slingshot Mechanics

Your primary tool for destruction. The slingshot is used to launch boulders and other special ammo at the enemy fortifications.

• Aiming

  Click and drag back from the slingshot to aim. The further you drag, the more power is applied to the shot.

• Trajectory

  A dotted line will appear to show the predicted trajectory of your projectile. Use this to aim for structural weak points.

Ammunition Types

Icon	Ammo Type	Effects & Interactions
	Fireball	Creates a large circular explosion upon impact and scatters Fire. Excellent against Wood, Oil, and Gunpowder.
	Boulder	Heavy and dense. Punches deep into structures, piercing through materials before exploding. Best for breaking Stone and Metal.
	Splitter	Tap the screen while in flight to split into three smaller projectiles. Great for covering a wide area or hitting multiple weak points.
	IceBomb	Freezes nearby Sand and Water into brittle Glass upon impact, then shatters them, causing structural collapse.
	Lightning	Creates a small explosion at the impact point and calls down a massive vertical lightning bolt from the sky, destroying everything in a column.
	Tornado	Does not explode conventionally. Instead, it creates a vortex that violently scatters loose Debris and Sand outward in a wide ring.
	Nuke	The ultimate tactical megabomb. Causes a colossal, screen-shaking explosion, spawning fire and scattering debris across the entire map.
	Laser	Fires a highly concentrated energy beam that instantly pierces a thin line through the entire level structure, destroying anything in its path.
	Black Hole	Creates a lingering vortex that sucks all loose falling particles (Sand, Water, Debris) towards its center for a few seconds before imploding.
	EMP Grenade	Instantly disables and deletes all Sci-Fi and Electronic tiles (Forcefields, Nanobots, Batteries, etc.) in a massive radius.
	Purifier	Releases a cleansing wave that neutralizes bio-hazards (Virus, Poison, Slime, Radioactive), converting them into harmless Water.
	Acid Flask	Shatters on impact, splattering highly concentrated Acid everywhere. Excellent for melting through thick Metal and Obsidian.
	Water Balloon	Splashes a massive amount of water. Puts out raging fires, cools Lava into Obsidian, and washes away Mud.
	Transmuter	A bizarre magical projectile that scrambles all materials it touches into random new materials! Very unpredictable.

Levels

• Procedural Generation

  The game features an infinite number of procedurally generated levels, with 35 distinct architectural styles (from floating pyramids to twin towers).

• Win Condition

  To win a level, you must destroy all enemy entities by crushing them under falling debris or hitting them directly with projectiles.
