I have one existing, shelved browser project that may fit your small-project request: NebulaKit Lightkeeper, a six-chart mirror-and-beam puzzle prototype.
Complete playable demo: https://nebulakit.itch.io/lightkeeper
Turn mirrors so one continuous beam passes through every star and reaches the moon. The six charts progress from one reflection to crossings and a return path; hints, undo, reset, replay and browser-local saves are implemented. It is a self-contained HTML/CSS/JavaScript project, with inline SVG/CSS visuals, system fonts and no third-party engine or art/audio pack bundled. No live AI or game server is used. The optional feedback link opens itch.io.
Code, puzzle drafts, interface text and verification scripts were AI-assisted, as disclosed in the game. It is already publicly available free; I am not claiming sales or an established player audience. Further game production is parked.
I have prepared the exact source file, play/development instructions and the two existing verification scripts as a candidate package. Indicative asking price: US$25 for this current project, subject to agreeing the files, rights scope and payment terms. No new development, accounts, customer data, other products or the NebulaKit brand would be included.
Your exclusive-rights requirement needs clarification before any agreement: existing publication/permissions must be respected, and I am not promising exclusive copyright in AI-generated portions or exclusive availability of existing copies. If the AI-assisted provenance and existing public release fit your plans, the complete demo is available for your assessment and we can discuss an appropriate scope. No rights or payment terms have been agreed.
