Your graphics were wonderfully balanced, with just enough detail to really encourage suspension of disbelief. It's easy to focus too much on the main subject of an image, and leave backgrounds too vague and empty, but you avoided that trap very well.
I also liked that most of the right materials for each toy could be collected from the various storerooms. But there's a fine line between a low-level puzzle that draws the player in, and annoying busywork that pushes them away, and it's a line that moves depending on the player. For me, having to ask Neldor about each child individually was a step too far, while looking up the requirements for each toy didn't feel as tedious since I could focus on one or two toys at a time. It may be that the magic list backfired a bit there, since it really highlights the repetitive nature of asking about each child.
Other than that niggle, the puzzles were well thought-out, and I mostly found the solutions without too much hair-pulling. The game was very enjoyable overall, and absorbed me quite thoroughly while I was playing it.
