Awesome game. I think the full potential of the game comes out in the final level, which had me trying multiply times to manage all my routes and prioritize certain enemies. The way you have to monitor your hose is a mechanic I've never seen anything quite like, making this easily one of the best maze games I've played. I was disappointed that there weren't more levels... but I also think I would have liked more smaller levels instead of ramping the difficulty up by making things bigger.
The art was pretty good, very charming. Some simple and low-key music would have helped.
The enemies having random movement was a little irritating sometimes -- maybe you could toy with certain enemies having more predictable movements, and telegraphing them in some ways?
Fullscreen, my game went outside the borders.
The tutorial text on level 1 also blocked my visuals.
