Nelly Jellies : Cozy Merge

Description

Game Overview

Name: Nelly Jellies (Bubble Merge)
Concept: A cozy arcade merge game inspired by my daughter. Players launch jellyfish, match colors, trigger powerups, discover rare jellies, and chase high scores one quick run at a time.
Platforms: Web, iOS, and Android

Growth & Funnel Strategy

Web First: My website is not a landing page, it is the actual game. Players can start playing within three seconds with no account, download, or waitlist required.
Conversion Model: The friction-free web version drives discovery, while my native apps handle long-term retention and monetization.

Current Metrics

Traffic & Users:

  • 123k views this quarter
  • 19k active users this quarter on web
  • 11k active users in the last 30 days
  • 2.2k active users in the last 7 days
  • 1.5k native app installs

Timeline: 3 months live on web, 2 months on Android, 1 month on iOS
Revenue: Generates $100 to $200 per month ($136 in recent IAP revenue plus roughly $76 from AdMob)

Tech Stack & Development

Tools: Built using React, Vite, Matter.js, Capacitor, and AI assistance (initially Gemini CLI, later advanced models).
Workflow: I prototyped mechanics in the browser, used AI to turn rough ideas into small typed helpers and components, and tested physics by hand before deploying a unified codebase across all three platforms using an automated pipeline.
