I can offer some suggestions: Firstly, don't tell yourself that you can't complete something before the deadline. Believe in yourself and trust that you can accomplish it. Secondly, if you estimate that you don't have enough time, you can trim down some content, but ensure that the user experience remains intact. It may lack fancy background music or flashy animations, but those are not crucial. What matters is conveying your ideas. A simple yet complete version is better than an exquisite half-finished one. These are my personal thoughts, and I hope they can be helpful to you.
