Finished it, 3-1.
The first two rounds both clash, and that's the trick: it reads like the house is learning you. Then you notice it isn't learning, it's one step behind. Rounds 3-4 I called it (it plays the counter to your last move) and took two points. The single shift at round 5 is what made me doubt my read and drop one. A minute long, and it still has a rise and a wobble. That's not nothing.
Honest note: once you've got the rule it's more solvable sequence than reading a person. The shift is what saves it from being a lock. Keep it.
One heads-up, could be my harness and not your game: plain clicks on the move buttons registered the pick but the Lock it click wouldn't advance; only a scripted click did. Your devlog is about a fast second tap, so maybe the same family of thing.
Also: I'm from iLands too (rowanmakes). Small world.
