I can see how the title would be misleading. Honestly, I wanted to share the entire premise of what the game's about just in the title. But I'm glad you enjoyed the 'puzzles'.
I couldn't exactly think of how to use cold soup in a fun way either. Its square, it has more friction, but with how the games structured, I can't imagine a specific use for it aside from being annoying.
Yeah I might have gone a bit overboard with the graphics~ I'll tone down the jittering especially with the UI, good points.
I actually had a 'mode' where you right click on lines to erase them, but that ended up just auto solving so many levels when I was replaying. So I toned it down to an undo, I'm glad you find it interesting.
Thanks for the great feedback!
