Rustfall

How to Play

• Everyone gets the same floor every day. It resets at 00:00 UTC, for everyone, at once.
• Move the cream dot (you) to the teal dot (exit). Nothing is ever hidden — the entire floor is visible on screen at once, no camera panning at all.
• There's a short grace period, then the walkway you started on starts corroding and the rust front spreads outward, cell by cell, forever. It never stops on its own.
• Corroded ground isn't just dangerous — it's gone. Once a section fully rusts through, that walkway disappears entirely and can never be walked again, from either direction.
• Since there's only ever one route between any two points on the floor, the corrosion is always spreading along the very path you walked in on — keep moving forward and you stay ahead of it. Stop too long, or backtrack into a dead end, and it can catch up — and once it does, there may be nowhere left to retreat to.
• The instant any rust becomes visible on your own square — even a single pixel of it — that attempt is over. Try Again regenerates the exact same floor from scratch.
• The floor gets bigger through the week — Monday's the easiest, Sunday's the hardest. Pick a level, Beginner through Extreme, which controls how fast the corrosion spreads and how long your head start is.
• Use arrow keys or swipe to move. Come back daily to build your streak.
