The stamping was really satisfying, especially the sound effects when you get something right!
I played this on stream yesterday (video here) if you’re interested in watching a playthrough of your game. I realized afterward that I totally misunderstood the how the graphs worked (for some reason I thought I just needed to stamp if the line ended going up, rather than it ending higher than it started). My fault for not reading the instructions fully… 😅 I somehow got away with doing it wrong for a few levels though, which maybe also says something about society.
