Heart is in the right place, but needs more work! – Gravity App Review

I love phis games and toys, and I can play with this sort of thing for hours, but sadly, this toy simply lacks features. It is hard on the eyes as well, It feels like the devs focused more on the physics then on the person who was going to be using the app. the UI is ugly and Obtuse, and even after you read all the footnotes, the degree of Customization is quite limited. There are better options out there.
