🌸 Bloomhold

A tiny kingdom in the clouds.

Build by day. When night falls, the grey Gloom drifts in, and every one you paint bursts into butterflies.

A chill, candy-colored kingdom builder. Made to feel good slowly. Headphones on.

What it is

Bloomhold is a relaxed, low-poly tower defense you can play in any modern browser. You ride a fluffy creature called Floof across floating islands. By day you spend glowing sparks to grow a little kingdom. At night, soft grey creatures called the Gloom wander in along the paths, and your towers, lanterns and friends paint them back into color.

Nothing is ever lost for good. If the Gloom drains a building, it goes grey and regrows at dawn. There's no game over. If you want no enemies at all, there's Zen mode.

Features

• Five floating islands, each with its own palette, weather and musical key: Petalmoor (blossoms), Tidebloom (coral and rain), Emberwood (autumn leaves), Frostglow (snow and aurora) and Prismara (every color at once).
• A full day-night light show, from a candy sunrise through golden hour to a neon-violet night with stars, fireflies and aurora.
• Seven buildings with three levels each: cottages, flower fields, Paint Towers, Lumen Lanterns, Bloom Hedges, Sprite Groves and Chime Spires.
• A generative soundtrack that is synthesized live. It changes between day, dusk, night and battle, and every sound effect is tuned to the current key.
• Musical toys everywhere: riding through flowers plays them like chimes, clicking anything makes it wobble and sing, and you can catch shooting stars for a wish.
• Vibe mode: hide the UI, let the camera drift and watch time flow.
• Gentle onboarding that teaches one goal at a time, with range previews, threat previews and off-screen arrows.

Run it locally

It's a single static file with no install and no build step.

git clone https://github.com/YOUR-USERNAME/bloomhold.git
cd bloomhold
open index.html          # or: python3 -m http.server, then visit localhost:8000

The first load needs internet to fetch Three.js and the fonts from CDNs. Progress saves in your browser.

How it's made

Everything is code. There are no image, model or audio files.

Rendering	Three.js r160 with bloom, plus a custom shader for tilt-shift, hue drift and color grading
Shaders	Custom GLSL for the sky, stars, cloud sea, aurora, rainbow, water, waterfalls and wind-swayed grass
World	Procedurally generated islands, paths and terrain. Every tree, building, creature and critter is built from primitives at runtime
Sound	Web Audio API: generative pads, kalimba, bells, soft percussion, reverb and ambience, all synthesized live
UI	Plain HTML and CSS, with Shrikhand and Baloo 2 from Google Fonts
Tooling	No framework, no npm. A small Python script bundles the modules into one index.html

Project layout

index.html        the whole game, ready to play or deploy
build.py          bundles src/ into index.html
