I have fixed the UI, so I hope it's a lot clearer now! I agree that the goals are a bit vague at the moment. I'm planning to add a 'Daily Goal' or 'To-do List' UI to help players understand what to do next.
Also, I'm very sorry you got stuck. Thank you for describing the situation specifically. The game is supposed to show a panel with a button to the next scene once the bar is full—I assume that panel failed to appear? I will definitely investigate and fix this. Thank you so much for playing and for the bug report! I really appreciate it.
