Kate Cox writes: Bugs aside, the game doesn't always work. Some puzzles are more obtuse than they should be, and sometimes, even when they work in theory, something gets stuck in practice. There's a lot of irritating backtracking deliberately built in. Swapping tools and skills can be clumsy, and certain sections near the end overstay their welcome, slow down the action, and are just tedious. There is too much pixel-hunting when it comes to performing any action; finding the exact right spot to stand in order to have the option to act can be a pain.
