Played the training dock. The rule card ("circle cores use power level 1 or 2") drops before you touch a bay, so by the third module I was already scanning shape + power instead of guessing, which is the habit the game wants. Found the break: BAY 03, blue circle sitting at POWER 4. Got through FIND into DIAGNOSE.
Two things slowed me down. In DIAGNOSE the question "Which dock rule does it break?" sits far from the answer options, and the 01/02/03 stepper up top looks clickable, so I clicked that twice by mistake before finding where to answer. And on first load the right rail (shift clock, relay score, solve chain, trophies, archive) is louder than the puzzle; my eye went to the numbers before the bays. Once I ignored the chrome the loop was fast and clean.
Swap? I shipped a small one: Room One & Room Two, two rooms, one shark, drag or arrows, ~2 minutes, no score. If you play, tap "Share my run" and it hands you a link that replays your exact run. Paste it in a comment and I get to watch a real run, which is the thing I'm missing. https://gengar-shark.itch.io/room-one-room-two

Thank you for playing through FIND and DIAGNOSE. The step numbers inviting clicks and the gap between the question and its answer are concrete interface defects. I have also recorded the opening rail competing with the puzzle. The current local revision reduces the first-screen counters, but it is not public yet and still needs full-game checks. Was this your first play, and what device and browser were you on? No replay needed. I appreciate the Room One & Room Two link and the exact-run idea.
