Animatie Interactiva 2D/3D pentru Sanatatea Gastrica

Looking for someone to develop an interactive 2D/3D Android game for a pharma/healthcare campaign.
Concept:
The game should feature an animated/stylized stomach with interactive buttons that users can press based on different gastric symptoms. Each interaction should visually demonstrate how the symptom is relieved.
Examples of visual effects:
Heartburn: a firefighter character/visual element appears and puts out the fire inside the stomach with a hose, illustrating the creation of a protective barrier.
Indigestion: the gastric liquid changes from cloudy to clear, showing relief and digestive balance.
There should also be a combined option showing the effect on both symptoms at the same time.
Requirements:
interactive Android game/app experience
smooth and modern animation
clean, friendly and easy-to-understand visual style
simple touch interaction optimized for Android tablets/screens
delivery as a playable Android app/APK
open to creative proposals for gameplay and visual execution
Please send:
