Very pretty, the visuals and audio are extremely well polished.
:)
My only grievances are with some of the mechanics:
1) I did not enjoy the grab and wiggle - it felt very repetitive, and was the most common issue (it also trigger my wrist and should RSI; but that's much more of a "me" thing);
2) I don't think the pipes should have ends that go nowhere - it's confusing, and I had to learn by trial and error what the intended solution was (I also think the straight pipes should go either way);
3) in general, I found the game harder and more punishing than I expected - I'd rather fix everything once (or twice) and move than, rather than wait around, *wishing* for rats to destroy stuff (which I should not be rooting for, narrative-wise) so that I can fix the stuff to add to my count to progress (I also felt like the counts were too high considering how repetitive the minigames were);
4) the rat king is too hard IMO and has too much health - my first attempt dragged on and on, just barely coming back from the brink over and over, before finally losing; on my second attempt, I beat him by using a cheese strategy of hiding behind him and smacking (no recoil back there) while ignoring the damage to the clocktower entirely;
5) when time is up, it should interrupt you immediately in-mini-game - multiple times when I failed, I managed to just solve the puzzle a second or two too late, hear the satisfying success noise, and think "oh, I just made it!" before being disappointed;
6) some sort of ending to the narrative would be good - it doesn't even have to be visual, just a paragraph to say whether or not the clocktower settled down permanently, and to say whether the other dolls got back up or not - what would be enough.
That ALL being said, if the minigames got more tuning/playtesting (and there were more of them), and the narrative was expanded, I would absolutely buy this.
The world you have sucked everyone into is too charming not to.
I want to see more of Hickory and the other dolls - a lot more; and I'm prepared to pay to get it.
