Wow this was a stellar idea! The levels are really well made and this puzzle mechanic is super interesting. I think the whole underwater stylistic vibe fits really well too. If I had to suggest an area of improvement, I would say adding some more visual feedback to which block is going to spin in which direction when you drag would make the controls feel much smoother. Sometimes I felt like it wasnt responding to my cursor movements correctly. I really hope you guys make this into a full release because I think it has a lot of potential!
