Remix: HALDANE-4

Build a short horror browser game inspired by "HALDANE-4": a solo descent beneath the Antarctic ice shelf, told through an ASCII-art operator terminal.
Tech: a custom renderer that draws the world as ASCII characters on a canvas or in a monospaced grid. Single page; best on desktop with headphones, with drag controls on mobile.
Controls: WASD to thrust, mouse to rotate, Space for the light, Shift to cut the engine (to stay quiet). Click to 'initialize the terminal' to start (and unlock audio).
Gameplay: pilot a small sub through dark caverns, with the light revealing only a small cone of the world. Story beats come as terminal log messages as you go deeper. Something is down there; turning off light and engine to hide is part of the tension.
Audio does the heavy lifting: low hum, sonar pings, distant sounds.
Keep it short (10-15 minutes) with a clear ending.
Steps: 1) ASCII renderer + movement, 2) light cone and level layout, 3) terminal story log, 4) the threat and hiding, 5) sound design, 6) your own twist.
Make it your own: don't copy the original's name, art, text or code.
