I liked the design and the gameplay is very easy and B even captured four stars at once when riding the minute hand of the clock!
I used a different gameplay to capture the extreme left star then wondered if that could be used for them all and was the designed gameplay. Spoiler: Extreme left star used the move when B is in mid air but under the influence of the rotatable so that B can be swung left and right in an arc.
That star next to the rhombus was difficult to catch... in my case I didn't use any technique, I simply waited for B to touch the star during one of the turns... on several occasions B got stuck on top of the rhombus which made me have to restart... thank you @Kanchan yadav
