Hey! Thank you for playing! The pdf includes hints on the 1st page. The solutions start from the 2nd page. I created two separate ones now to avoid any further confusion. I hope you can still play it with the solutions available!
I tried it again, filled in the solution from the solution sheet, and got through the rest just fine! Loved it. I love these kinds of puzzles in general, and the vibe and aesthetic was lovely. The story didn't fully land with me, though. Anyway, great job!
