Please add a leaderboard. ### 1/5 — No instructions *2022-09-12* I opened this app, all it said was “Play”. No instructions. Not in the settings, nowhere to ask questions, nothing. Keep the ball in the box? Are you kidding? The ball just drifted right out of the box to the side of the screen, no matter if I moved or tapped the phone, the box- whatever. I don’t get the point of having a game without instructions and the only conclusion it gives you is to quit or play. ### 5/5 — Simple, Fun, Addicting *2021-06-24* I really love the concept of this game, especially because of how simple, yet hard it is. ### 4/5 — Cracking little game! *2021-06-24* Very simple to play but quite hypnotic. Looks good and it is lovely to see an app like this as completely free without adverts. ### 5/5 — Great Game! *2021-06-24* This game is amazing and pretty fun! The graphics are cool and the UI clearly took a lot of effort. Great game! ### 5/5 — Great design, simple fun! *2021-06-24* The game is very simple but gets difficult as you progress. The perfect balance of challenge and forgiveness. Excellent first app! ## Frequently asked questions about Boundary! ### What is Boundary!?
