Remix: Project_GENESIS.exe

Build a small, playable browser game inspired by "Project_GENESIS.exe" (Adventure, Simulation, Survival).
Concept: A voxel survival sandbox where the world is watching back — fight to see the morning, plant flowers when you do, and slowly find out why that matters more than you'd think, to something you haven't met yet.
Tone/hook (from the game's own page): A voxel based simulation environment featuring creative and diagnostic modes with multiplayer support and procedural world generation.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls (as seen on the original's screen): WASD to move, mouse to aim or look, Space to jump, Shift to sprint/dash, tilt controls on phone, drag to aim/move, tap on mobile, Esc/P to pause. Show them on a short how-to-play screen.
Multiplayer: the original is listed as multiplayer. Start with a local or bot opponent, then add online play (e.g. WebSockets) once the core loop is fun.
Core loop: include levels, stages or waves that ramp up, progress saved in localStorage.
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
