BeetleJump

Build a small, playable browser game inspired by "BeetleJump" (Platformer).
Concept: Climb to the top. Become the king.
Tone/hook (from the game's own page): Multiplayer beetle climber. Race to the top across 150 platforms, claim the summit throne, then ascend the cloud staircase to pilot a blaster-armed saucer as the Beetle God.
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): Space to jump, drag to aim/move, tap on mobile. 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 a visible score, a timer or round clock, an optional local high-score table.
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.
