Read full descriptionHide full description
A sculpture hangs in the corner of a dark room. Two lights. Two walls. Two shadows that refuse to agree. Turn it until both shadows land on their targets at once. Fix one and you break the other — the answer is the single position where both are true. No timers. No lives. No tutorial text. The room teaches you, and it hums as you close in. • 247 rooms across thirteen chapters • Endless mode — rooms generated on your device, running as deep as you want to go • Sculptures that look like nothing, until scattered fragments resolve into a duck, a cat, a moth • A daily room — the same puzzle for everyone, every day • The Workshop: stop finding the answer and start building it • Stars for precision, never for speed Play it slowly. It rewards that.

Verdict
The clearest difference is in-app purchases: duk. at none against In Two Lights's 1. In Two Lights's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price, update cadence and ads there is nothing between them.
