🌈 Beyond The Rainbow

A tiny 2D action-platformer created for js13kGames 2026, built around the theme Unicorns and Rainbows.

A powerful curse has stripped a Rainbow Guardian of its magic and scattered its seven colours across the world. Play as the cursed black unicorn, defeat the guardians, recover the colours, unlock their powers, and face the wizard responsible.

🦄 Story

Once, a unicorn protected a world filled with colour and magic.

A mysterious wizard wanted the power contained within its rainbow horn. Instead of simply stealing it, he cursed the unicorn and shattered its rainbow power into seven colours.

Now the unicorn is weak, corrupted, and almost completely black.

The seven colours have been scattered across different worlds and placed under the protection of powerful guardians.

Recover them all, break the curse, and restore the rainbow.

🌈 Seven Colours, Seven Powers

Colour	Power	Gameplay
🔴 Red	Fireball	Burns vines and enemies
🟠 Orange	Dash	Cross long gaps and escape attacks
🟡 Yellow	Lightning	Strike nearby enemies
🟢 Green	Grow	Create platforms and heal
🔵 Blue	Freeze	Freeze water and enemies
🟣 Indigo	Teleport	Blink through thin walls
🟪 Violet	Time	Slow the world down

The seven colours aren't just collectibles — each one changes how you play.

🖤 The Curse

The curse is part of the gameplay, not just the story.

Using colour powers increases Corruption. As corruption rises, the unicorn begins to glitch and the screen becomes increasingly distorted.

Managing power and corruption adds a small risk/reward element while keeping the main objective simple: recover the seven colours and break the curse.

🎨 Technical Approach

This game was designed around the 13 KB challenge.

Instead of large image assets and sprite sheets, the game uses:

• HTML5 Canvas
• Procedurally drawn characters
• Procedurally generated environments
• Reusable enemy and guardian systems
• Particle effects
• Synthesized sound
• Compact JavaScript
• Data-driven level progression

The unicorn, enemies, guardians, environments, effects, and story scenes are drawn directly with Canvas to keep the game extremely small.

🎮 The Final Goal

Recover all seven colours.

Become the complete Rainbow Unicorn.

Defeat the wizard.

Break the curse. Restore the rainbow. 🌈🦄
