Glow Stack

# Glow Stack

**Merge to shine.** Drop matching glowing bricks so they touch, climb tiers from I → Gold → Max, and clear **50 portrait levels** in your browser.

You *can* lose — ceiling hits, rising sludge, and drop budgets keep “just drop straight” from being a free win.

## Features

- **50 levels** on a gentle, always-completable difficulty curve

- Clear **OBJECTIVE** + live **Progress** every level

- Fail pressure: ceiling, sludge rise, move budgets

- **10 free skins** unlocked by progress (cosmetics only — never paywalled)

- Touch controls + keyboard (←→ / A D, Space / ↓ to drop)

- Saves progress in your browser

## How to play

1. Move the falling brick left / right

2. Drop it onto matching color + tier neighbors to **merge**

3. Hit the level goal before you top out or run out of drops
