Hi, can you give us more details about your issue? And are you on Windows, Linux, or Mac?
In order to upload files onto Itch.io they need to be compressed into a zip file. Luckily they are super easy to extract; all you have to do is right-click the file and choose "extract here" and then double-click the DeliciousDate.exe in the extracted folder to play! Apologies for the inconvenience!
