All it means is that this is too far off the standard - you can resubmit it assuming you make enough of a radical change to bring it up to the necessary standard.
The reviewer currently sees that there is too much to feedback on so raising the quality as far as it needs to be will in effect make it almost like a new file.
In your case you need to sort the styling and execution out a lot. But you would also really need to have different layouts, features etc. to give it a proper premium feel and be able to compete.
It’s been discussed thousands of times but feedback on files a long way from the required standard will never and should never happen for several reasons the main ones being:
There are literally tens - hundreds of thousands of submissions monthly. Even a few lines would slow the process down and already many believe it is too slow as it is
The main reason being if someone believes their file is ready when it is so far off the mark, then there’s a good chance (of course not every case) that feedback would be pointless as the author may well not understand or be able to action it properly.
If an author was told to “improve typography” (as an example) and they did so (in the authors opinion) but it was still deemed too weak then this is going to be far more frustrating and potentially cause greater issues than avoiding feedback all together until an item is closer to the right quality.
Hope that adds some clarity.
