Kerfline: One-Tap Gravity Flip

A dot. A wire. One tap. The wire has two sides. The dot rides one of them. Tap, and gravity flips it to the other. That's the whole rulebook — everything else is what the wire does to you. Wires curve. They spiral. They split, and the side of the wire your dot is on decides which prong it takes. Spikes wait in your path with just enough warning to dodge them, if your timing's honest. Gaps open under the wire and the dot has to cross on nothing but physics. Nothing here is random. Every hazard is exactly where it was the last time you died, so every death is yours to own. One touch and it's over. Restart is instant — no loading screen, no "tap to retry." 70+ hand-built levels get harder in ways that are fair and never in ways that are cheap. Some of them are the hardest one-tap levels you'll play this year. A few will take you a long time. That's on purpose. Every level tracks your deaths and shows you the percentage of players who've actually beaten it — sometimes it's a humbling number. A separate timer clocks your best runs, but the leaderboard that matters ranks fewest deaths, because two players on the same route tie on time and only one of them died less. Clear a level and you can share it — your death count, your completion percentage, one tap. Cosmetic trails and skins are earned, never bought: clear the hardest levels, finish one without dying, or clear the whole set. Proof, not decoration — and not one of them changes what a level asks of you. Kerfline is free with ads. Now and then, after a death, a short video ad appears — most of the time you can choose to skip it. Nothing in the game is for sale — there are no in-app purchases, and every cosmetic is earned. One wire. One tap. Plenty of ways to lose an afternoon.
