Find it. Circle it. Collect the stars.
Reef Spot is a cheerful spot-the-difference game starring Ollie the octopus detective. Two almost identical scenes, a few hidden changes and one magnifying glass: players tap the differences, earn up to three stars per level and travel through five colourful worlds. You get a finished game with menus, progress, sound and music, plus the complete source code to reskin, translate and publish as your own.
A guided start and a lot of juice
The first level teaches the game: Ollie explains every step in speech bubbles while a pointing hand shows where to tap, then the player is on their own. Found differences get animated circles and sparkles, mistakes are soft, and each level ends with a victory ceremony.
5 worlds, 50 levels
Reef, Kelp, Wreck, Ruins and Palace: ten levels each, with their own scenes, props, music and a background that changes with the world. The level screen shows one world at a time with arrows on both sides.
Helpers when you need them
A pearl magnifier finds one difference, a lantern fish shows where to look and the periscope peeks at all of them. Helpers are limited, so using them is a choice.
