The mini-games
Each mini-game has 18 levels. Players earn coins and use them for Tivvo’s clothes, decorations and new locations.
Mathematics has its own 30 stages, in addition to the mini-game levels.

Clothes, rooms and time with Tivvo
Players can try items on Tivvo before buying them, arrange decorations in the yard and room, and work through twelve care sessions. Purchases and progress stay in the local save.
Other rooms and settings
These are real 1.0.0 game captures with the normal starting balance of 25 coins. Locations were unlocked temporarily for the screenshots. The game interface shown here is English.
What I’m selling
I chose to sell the editable project rather than publish and run the game myself. It has not been publicly released and has no verified audience or revenue.
Files included
The private Android signing key stays separate until an agreed secure handover. No store, email or social media account is included.
Technical details
Current installation issue
Google Play Protect has reportedly marked the APK harmful on a Samsung Galaxy S24. I haven’t confirmed the exact warning or its cause yet. The APK’s signature is valid and it requests no permissions, but those checks do not prove safety. This issue is unresolved; do not bypass the warning. There is no APK download on this page.
Testing and limitations
The package includes the actual test report: release builds, core-rule tests, emulator gameplay, a save-preserving update, and layout and language checks. This is not a guarantee for every physical device.
Development and rights
AI tools helped with the code, artwork and audio. The available art sources, audio generators, development notes, prompts and asset/licence records are included. A supplied music recording without documented commercial permission was removed.
The sale agreement will need to define which rights I can transfer. Exclusive copyright in AI output and registered trademark rights are not claimed.
