(Disclaimer: I played the v1.01 build, so I have no idea about the new and improved experience 😅)
Really well made! I had a good time playing this demo. Hours went by in a flash~
The puzzles were fun, even for someone like me who's bad at them! Having an in-game notes feature helped quite a bit, and the hints helped me when I got stuck too! (which happened very often) ...though there was one particular puzzle that I got stuck on even with the hints (probably the one that's updated in v1.02)
Itch is a big meanie and doesn't let me spoiler tag things, so I'll just say that the endings were interesting! Can't wait to see how things shake out in the full game.
(side note...based on their surname, are Noah and Vivian meant to be Cantonese? 👀)
