vovu comes from Ugur Kubat. The object is to tap on the big red circles to make little red circles rotate in order to free up the green circles. Where things get complicated is when there are multiple big red circles. Unquestionably, the overall design is very artistic. It's a very calm game. Similar to Hook from 2015.
There are 70 levels and I've done 53. There are ads, but they are minimally annoying.
