The premise is solid (or liquid, haha), the description of each level is poetic, and the rest of the game flows like music. However, I found the difficulty went up considerably at level 4-5, as it felt like I had to be perfect with the platforming or else I failed. Moving from left to right took longer than I felt comfortable with, and there was one level with an up arrow that I could not figure out how to finish. I played the web version and there was no cursor. Let me know if I missed something!
