Twinkle Twinkle Little Star by Rewind Game Studio is an app targeted at younger children. It consists of a few scenes that fly by as the first verse is narrated.
The drawings are beautiful, and the animation to move from scene to scene (a fly by) is unique and engaging. It appears to be a human narrating and the background sound is soft and soothing. You should be able to easily use to this app as background noise for putting children to bed.
As for grips. I wish there were more verses, more scene and more narration. I wish you can adjust the volume of the narration or the background sound. Otherwise a decent and beautiful app.
I received a Demo Review copy, and as such it has those words across all the scenes (as seen in the photos). Rest assured the paid version does not have these words. It also has no ads or in-app purchases.
Available on the Google Play store for .99c.
