Instead of uploading the .zip I took the .exe file.

Is there an admin or something that can help me change the game files?

You can't play my game without the other files...

I did the same thing, dragged it in a panic and didn't realise. I just made a new project with the proper zip file and changed all of the submission text etc to point t the new link (https://sundriedoctopus.itch.io/basement-knight-1-0).

People might use it so it might be worth a go for you too :)
