Is the game broken?

The competitive mode started at 7 o'clock. After watching videos, I could only last ten minutes. Now there's only one item per stage left to clear. It's even more ridiculous now. Whether you clear the stage or not, items aren't being added anymore...... Are they afraid all the gold missions will be completed? 🙄🙄 How am I supposed to clear the remaining gold missions, over 300 a day like this? 🙄🙄
