ORBIT is a gravity simulator at the heart of a puzzle game. Launch planets with a flick of your finger, and try to get them into stable orbits around black holes. Can you make enough orbits to progress to the next level? New: ORBIT now features a Sandbox (paid) where you can create your own levels! Control time, disable collisions, and paint with gravity. Publish your creations to the world for everyone to play. • 45 free levels, with new mechanics are introduced over time — like repulsive black holes and planets with their own gravity that attract each other • Play community-created levels — virtually limitless content made by other players, all completely free • Launch as many planets as you like, and watch the mesmerizing orbital mechanics unfold • Planets leave colored traces, so that at the end of a level you will have created a beautiful piece of art • See the future trajectory of a planet before you launch it • Play in an environment of smooth, minimalist graphics while listening to relaxing classical piano Follow on Twitter: https://twitter.com/highkeygames Follow on Facebook: https://www.facebook.com/highkeygames

Verdict
The clearest difference is in-app purchases: Morse Code Tower Defense at none against Orbit's 7. Orbit's advantage is update cadence (every 2 months vs every 6 months). On price, ads, device support and iOS requirement there is nothing between them.
