Very amusing deduction puzzle, I enjoyed solving it!
I have a few suggestions
- It would be nice if the image tiles would disappear from the left when assigned to a target, I understand this is not quite possible for the names thanks to an exception but even just for the images it would help a bit with the feel of solving (without ruining anything about the puzzle or its difficulty).
- Being able to put back tiles by just dragging them to the left (instead of onto the exact tile) would be handy.
- Think you should be consistent with how one can close overlays by clicking on the background, currently the lost-and-found and the labels can only be toggled via the buttons and the speech bubbles can only be closed by opening another one or clicking the same person. Additionaly, when an overlay is opened (like the sign) clicking on the guest book in the background should just close the sign maybe, not open the quest book. This would make navigation more predictable overall and remove a bit of friction.
I think the two frame switching is a little bit jarring as it is, one simple improvement might be to have each character/animal have it’s own timer that switches between the two frames separately, some less frequently than others, some only on hover etc. This might make the scene feel more alive without having to do additional art.
