Click (or press) around the blue circle (that's you) to spray water droplets in the desired direction. If you touch the edge, you have to restart the level. Light blue walls make the droplets bounce off. If a droplet touches red, you also have to restart the level. There are 10 levels in total. Some may be ᴠᴇʀy ʜᴀʀᴅ.
Idea, code, and art are completely by me. All levels are 100% possible, but as you progress, the levels get harder and harder. By the way, you can "shove" through walls by holding.
