Neon Idle Skill Tree – HTML5 Upgrade System Template (Passive Abilities)

## Neon Idle Skill Tree – HTML5 Template (Rebrand & Resell)

A neon-styled **idle skill tree** HTML5 template where gold is generated

automatically over time, and players invest in permanent upgrades like Power,

Speed, Crit Chance, and Efficiency. Each skill has scaling costs, levels, and

different effects that change how gold grows.

Perfect for beginners, students, teachers, or template sellers who want a clean,

easy-to-expand idle mechanic for HTML5. This system works great as a standalone

idle game or as a component inside a bigger project (RPG, clicker, dungeon,

auto-battle, etc.).

Everything runs inside a single HTML/CSS/JS file and is simple to reskin,

modify, or extend.
