About Rotworm Killer

A browser-based idle/clicker RPG inspired by Tibia, built entirely with vanilla HTML5, Canvas API, and JavaScript — no frameworks, no dependencies.

Gameplay

• Click rotworms to attack them; land kills for gold and experience
• Bosses (Versperoth) spawn periodically — frequency configurable via the Skill Tree
• Uber Bosses appear every 50 kills once unlocked — tougher, bigger rewards
• Weapon progression across multiple tiers — upgrade when you can afford it
• Offline progress simulation: earn gold & EXP while away (up to 8 hours)

Skill Trees
