Paper Harbor is a free browser puzzle prototype about loading the right cargo in the right order.
Crates arrive in a fixed queue. Two ships are at the berths, each asking for particular colours. Load a crate, put it in the limited Early arrival bay, or send a full ship away to make room for the next one. The bay gives you room to experiment, but it can fill up at exactly the wrong time.
The evaluation includes nine fixed manifests, English and Spanish text, undo, restart, and buttons plus keyboard shortcuts. Progress lasts for the current session. The layout has been checked in desktop and narrow browser windows; physical phones and tablets have not been tested.
I'd welcome feedback on which later manifest first feels confusing, and whether the holding bay and departure controls are clear.
