# 🚀 Naddie Jump — Monad Edition

A vertical endless jumper inspired by Doodle Jump, themed around the **Monad Blockchain** ecosystem.

Play as **Naddie**, the purple Monad mascot, and jump your way up through blockchain blocks while avoiding bugs, high gas fees, and collecting power-ups like the Propeller Hat and Fast Transaction Rocket!
