Finn's Reef Run
A cheerful, fast, family-friendly side-scrolling shark adventure. Slide to swim, gobble up little fish for points, chain combos, and dodge the ocean's hazards — all wrapped in a hand-drawn flat-vector art style with a jolly sea-shanty soundtrack. Installs to your phone's home screen and plays
Finn's Reef Run is a one-thumb arcade game about a happy little shark cruising an endless reef. The world scrolls toward you; your only job is to guide Finn with your finger (or mouse) — chase the colorful fish to rack up points, build a combo multiplier by eating them in quick succession, and weave around the junk drifting through the water. Grab a green dash bolt to blast forward at full speed, and scoop floating hearts to win back lost lives.
It starts gentle and forgiving, then gradually turns up the heat: obstacles grow bigger and more frequent, the current speeds up, and new hazards join the reef the longer you survive. It's easy to pick up, quick to play, and built to slip onto your home screen like a native app.
Highlights
- 🎮 One-thumb controls — slide anywhere on screen; the shark glides just ahead of your finger so your hand never blocks the view.
- 🐟 Chase & feast — eat fish for points and chain them for an escalating combo × multiplier.
- ⚡ Dash power-up — grab the green bolt for a burst of speed and brief invincibility.
- ❤️ Health pickups — heart bubbles restore a lost life (or bonus points if you're already full).
- 🌊 Gradual difficulty — sparse and easy at first, ramping up in size, speed, and density over time.
- 🎵 Original sea-shanty soundtrack — a bright, jolly tune plus chompy sound effects, with a one-tap mute.
- 🌐 Two languages — English and Bahasa Indonesia, switchable in Settings.
- 📱 Add to Home Screen — installs as a fullscreen landscape app and runs completely offline.
