Wow, quite the interesting puzzle game you got here: the usage of Pinokyo's extending nose was rather inventive and I enjoyed seeing the twists and turns it added as the game progressed! Puzzles were really well-designed and it felt like they intuitively tutorialized all of the tips you needed to learn well. Apart from that, the game was also decently juicy and smooth-feeling, and had some nice humor with all the quips that came up and the amusing ending.
While I enjoyed my time overall, I was a bit conflicted about the mechanic where you can shorten Pinokyo's nose by snapping it during a turn.
Part of me likes the mechanic in theory since it not only adds another layer to the puzzles to think about, but it also provides the player a bit of wiggle-room where they can recover from a slight error, similar to platformers which let you get a bit more distance or change your direction slightly during a jump by punching or kicking in mid-air.
However, whenever I needed to shorten my nose, it kinda felt like cheating, like I shouldn't be doing it. I think it was due to the fact that a) the initial puzzles and theme set a precedent that you gotta live with your lengthens and b) getting the nose to snap to a shorter length felt really fiddly and hard to pull off: I'd just mash the jump and turn keys and eventually it would happen. It just felt awkward.
Ideally, I think the puzzles should be built around not being able to shorten your nose: lengthening the nose should be a careful consideration as the player needs to decide when to lengthen it and how long to make it without getting stuck, planning their whole trip out. It makes sense since the puzzle rooms are so short and the nose is reset every room: getting stuck with a too long nose would only ever put you back a few seconds. But I could be wishing for something that I'd regret getting, perhaps, haha! Well, it's food for thought!
A short and sweet adventure that, while I enjoyed it, would've loved to see even more twists and mechanics get introduced!
