Five colours · Five lanes · One crystal

A co-op action tower defense for up to five players. Hold the crystal at the heart of the pentagon against every colour of mana.

The game

The crystal must not fall

A crystal stands at the centre of a pentagon, and five lanes lead to it, one for each colour of mana. Each wave the colours send their warbands. Melee screens hold the front, archers form a shell behind them and mages cast from the core.

You pick one of five classes and fight in third person with its weapon and the spells of the colours you choose. Between waves your team spends its shared mana at Upkeep. If the crystal falls, the run is over.

Five colours

Every lane is its own world

The lanes follow the colour wheel, so each one borders its two allies, and allied warbands can arrive together and charge as one. Each colour brings its own biome, its own army and its own boss.

Features

Built for a full table

One to five players

Host, join or play solo. Five players, five lanes, five colours: with a full party, each player usually holds their own colour's lane.

A pentagon skill tree

Seventy skills across five colours, each with five ranks, in three rings that open as you invest. Invest in two neighbouring colours to unlock their guild node.

Five classes

Warrior, Knight, Barbarian, Archer or Mage. Each has its own weapon, its own way to defend itself and four class skills on top of the colours.

A tower for every colour

The Ivory Tower shields your allies, the Glacial Fortress slows and freezes, Bontu's Monument raises the dead, the Goblin Sharpshooter shoots fast and hard, and the Hornet Nest draws the wave and stings back.

Shared mana, personal builds

XP is shared, so everyone levels together and nobody can steal a kill. Skill points are yours to spend. Mana belongs to the team.

Upkeep between waves

Spend the team's mana on Myrs that harvest the wells, on extra skill points and on enchantments. In a team, enchantments need a majority vote.

Readable bosses

A boss arrives every fifth wave and fights in three phases. Every attack is marked on the ground before it lands, and bosses drop equipment for the whole team.

Nights are dark

A full day and night cycle. After sunset you see by the crystal's light, by torches and glowing mushrooms, and by your own spells.

Wild beasts

Away from the lanes, every biome keeps its own beasts, whatever the waves are doing: spinebacks, ravagers and terrors in the colours of their land.

Get it on itch.io and install it with the itch app: it keeps the game up to date and downloads only what changed. Gather up to four friends, or hold the pentagon alone.

The zip: unzip it and keep the DLLs next to the .exe. The build is unsigned, so Windows may warn you on first launch. Click More info → Run anyway.
