This is a nice game! I initially expected it to be pretty boring an uninspired when I saw that it was a pipe game, but I was pleasantly surprised to see that it was actually quite interesting and challenging. The mix of moving and rotating mechanics is a breath of fresh air, and the level design does a good job of showing off how these simple mechanics can make complex puzzles (the last level in particular had me thinking for quite a while). The difficulty curve was also great, as I always felt challenged but never reached a point of frustration. The game doesn't overstay it's welcome, but it would probably need some new mechanics to shake things up if you ever go back to it and add more levels. Overall, I had a lot of fun with this game, and it was a nice twist on the pipe game concept. Nicely done!
