Remix: Last Known Position

Build a small, playable browser game inspired by "Last Known Position" (genre not listed).
Concept: A top-down stealth game set on a lightless alien world. You wake alone on an alien world forsake by light. And something has gone terribly wrong. You are blind - your only tool is a short-range LIDAR ping that gives you a brief peek into to gloom. Use it to map your….
Tech: use plain HTML, CSS and JavaScript (or a lightweight engine you know); 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, arrow keys, an on-screen joystick on mobile, tap on mobile, gamepad support. Show them on a short how-to-play screen.
Players: start single-player (the original's player count is not stated in its listing).
Core loop: include levels, stages or waves that ramp up.
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.
