Well done and well done. I've never had this much plumbing fun since the early mario games.
The music, amazing, the very simple pixel art style, also amazing. The game was also short and to the point, I also love how you incorporated the "call of duty" like health bar, the gameplay felt a lot more fun that way.
Also, I would like to point something out. It's not an issue but, when you get the ability to fix the pipes, it turns out that you can fix it without being very close to it. Which feels a bit weird.
Nevertheless, great game, hope to see more levels in the future. ^^
