These games are all the same and none of them are good. I don't know what happened to mobile between 2012 and 2016 to make most games derivative trash like this.

Was fine until I reached a point where you literally could not beat the levels without having to watch an ad to unlock an extra tube.

This might be the first and only time that I download an android game I saw on an add, but it was pretty decent! It's a simple puzzle game that is also kind of relaxing, ASMR style.
