This was very zen and I enjoyed it a lot well done. I did occasionally have an issue with the very larg bubble not always recognsing smaller bubbles and so sometimes they overlappeed instead of merging but this wasn't frequent and didn't affect my enjoyment. Also t was a bit jarring if he bubble got caught on an edge of the scren then it would shake and the noise was very unpleaseent.
Will definitely play this again when I want to relax for a few minutes.
