Been a while since I played a liquid puzzle. The puzzles seemed pretty good. The variety fills out the content well and didn’t feel repetitive. B2 took a bit to figure out and I had to write down the fractions, but the rest were doable mentally.
For dialogue changing visible_characters_behavior to Characters After Shaping to make text wrap to the next line without moving words halfway through makes it much easier to read and looks better.
There’s a small bug where the pipe out becomes unselectable if you click it while dragging a pipe.
The art is a little too noisy for my tastes, but it is interesting to look at. It would be nice if the size and goal fractions could be shown somehow without hovering over the container so that I wouldn’t have to keep hovering back and forth to see which is which.
Overall felt fun to play. Good work.
