A fantastic puzzle game with light adventure and minimal hidden object bits. The story's a throwaway intended solely to provide flavour and context, but it's presented beautifully.
One glaring issue: several users, including yours truly, encountered a game-breaking bug in a projector puzzle very late in the game. An object required to progress in the puzzle and hence finish the game fails to materialize. For some strange reason, this is also the only unskippable puzzle in the game (so far).
If an update fixes that bug, this is definitely worth full price. I bought it on sale, and while I'm miffed that I'll have to YouTube the last few cutscenes s, I feel I got my money's worth. YMMV.
