Hey what a life saver! I loved this game but got absolutely stuck at the end—completely missed the interactive pillars in the cart cave, assumed I needed to access the cart by opening the metal door with a key that I'd get by solving the spiral, and of course I couldn't understand why I was unable to brute force the spiral combination. Thanks!
Of course! There's never any shame in admitting you're stuck, and I'm glad to have helped you out. A long time ago I decided that using a walkthrough to finish a puzzle game doesn't necessarily make the experience less valuable, because for me it often doesn't make it less fun or interesting, and I can appreciate puzzles I couldn't solve and ones I never even would have seen. Plus, often if your intuition about a puzzle doesn't match the developer's intuition and how they expect you to approach it (e.g. assuming "this looks weird I probably need a key" rather than trying to interact with it first), it can make it completely impossible. I often recommend trying to get a sense for different developers' puzzle logic if you can't parse it, by playing through some of their games with walkthroughs, before attempting to beat maybe a harder one on your own.
