I liked it even though I normally find these types of sliding puzzle levels frustrating. Spoiler I couldn't figure out how to get the last star until I rotated the view! Spoiler Then I got B to drop by moving a slider out of the way.
@Pratik Bhalerao to get the last star on the ground yes, but you could also tap a platform, move it at the last second and then the yellow bot will be able to get the star
