About Rooms of Secrets
Unity Android puzzle game: 60 rooms, 5 languages, full source project for sale
Rooms of Secrets is a portrait 2D puzzle game for Android built in Unity. Asking price: EUR 6,000, negotiable, for a one-time transfer of the full project and transferable rights. This is a pre-launch project sale; no revenue, customer base or download metrics are claimed. CONTENT 60 rooms and 380 puzzle stages with algorithmically generated variations. Kids: 10 rooms, 15 minutes each, difficulty 2/5. Expert: 25 rooms, 30 minutes each, difficulty 3.5/5. Legends: 25 rooms, 45 minutes each, difficulty 5/5. English, Greek, German, French and Italian.

Wrong answers remove 3 minutes in Expert or 5 minutes in Legends. INCLUDED Unity C# source, game data, artwork, Android icon, audio with licence notices, setup tools and handover instructions. Core gameplay works offline. This is a 2D logic game, not real-time 3D exploration. DEMO The homepage link downloads an earlier Android gameplay APK, made before account login and paid-content locks were added. It demonstrates gameplay only, not authentication or payments. The delivered source is newer than the demo. BUYER SETUP Firebase email/Google authentication adapters, Unity IAP integration and purchase-verification backend source are prepared but not activated or live-transaction-tested. The buyer configures and owns Firebase, Google Play and payment accounts, completes release testing and handles publication and service costs. Seller payment accounts and ongoing hosting are not transferred. Cloud progress sync and an iOS release are not included. PROPOSED END-USER PRICING Kids free; first Expert room free. Remaining 24 Expert rooms EUR 20 once; Legends EUR 25 once; combined package EUR 40 once, without a subscription. Illustration only: 200 purchases x EUR 40 = EUR 8,000 gross customer spending, before commissions, taxes, refunds, operating and marketing costs. This is not a forecast or guaranteed income. Development and artwork used generative tools. Third-party music/fonts retain their licences and are not exclusive project property. Final transfer scope and any additional support are agreed separately.
