The UI of the activity (placements of elements) is to be laid down.
- In horizontal mode there will be a play button, and an undo button (and a toggable sharp/flat icon for levels which needs them) on the right side of the screen and vertically centered for easily accessibility. On vertical mode, it will be moved to the top, under instruction box.
- Below it, there will be a staff.
- Below the staff there will be the piano.
In the bar, there will be 2 additional icons: Reload button to restart the level and a configuration icon to change the difficulty mode.
