I will hand you a set of static PNGs and, inside Unity, I need each character or prop to react when tapped. A single tap should call up a short environmental effect—think gentle rain, drifting snow, mist, or a faint halo of light—along with any subtle secondary motion that sells the moment. All artwork is supplied; your focus is wiring simple touch input to lightweight animations, exporting the finished scene so it runs smoothly on both desktop and mobile builds. If you prefer a different pipeline you can mention it, but Unity is my default target so please be fully comfortable there. Please highlight relevant Unity experience when you reply and note any past projects that involved particle systems, sprite rigging, or lightweight interactive loops. Deliverables • Unity project folder with organised assets and scenes • Playable build (Android, iOS or WebGL) showing each image responding to taps with the assigned environmental effect • Brief read-me explaining any custom scripts or shaders Clean, commented code and tidy hierarchy are mandatory acceptance criteria.
