I love the minimalism and aesthetic. The game is simple and satisfying. Great job!

One thing I would work on is helping the users a bit with the difficulty. It's hard for people to naturally understand angles of things bouncing off of complex features.

Maybe show transparent lines from past attempts that failed? Tracing how the ball bounced and where it went? This would help the user learn and make small adjustments by having more information on past attempts.

What do you think?

That's a very generous review, thanks! I'm on-board with your feedback for the most part.. and I'll see what I can do about deploying on App Stores. For now, the game is playable on mobile browsers on Itch.io.. and my website: Twelve47Studios.com
