Okay? is a minimalistic game I stumbled upon in the Play Store when trying to update a misbehaving app. I really enjoyed it because it was free and the ads were entirely optional. The task is to angle a small, black ball to bounce off of flat, simplistic, white geometric shapes that disappear when hit (the black shapes do not disappear!). The ball can start in any position on the screen and you are free to choose any direction in 360°. Once you have chosen a starting position and angle, the ball will move in straight lines only. An example of a starting position and trajectory for the ball (circled in red) is given in the image below, but it is not the solution for this level, which has one unique solution. When your ball hits a thin white line, the line disappears and your ball passes through unphased, but other than that, typical frictionless kinematic rules apply. If the ball crosses the edge of the screen, you have to start over (unless all the white shapes have already disappeared). The app can be found on Google Play and the App Store for iOS. The app has not been checked by Geocaching HQ or by the reviewer. If you choose to download and install the app on your phone, you do so at your own risk. You don't by any means need to download the app to solve the puzzle, but it doesn't hurt either. Okay?
N 63° 24.5?? E 10° 25.8??
[Edit] Jun 6, 2021: Due to a minor typo, the solution checker didn't give the right answer, even when the puzzle was solved correctly. The coordinates have been updated and the solution checker should work now.
