HI! Unfortunately, you gave us the .project, which doesn't store any of the files, just the basic project setup. If you would like to export, you will have to go to:
- Project - > Export
- Click Add -> choose the version you want to export for
- It may pop up a warning that says you need a template first. You will want to download the suggested one.
- if it's web, make sure when you export the project name it index, and you can run it in the browser of itch.io
- if it's an exe after the template is installed, you can just export it and it should work.
- Pop it in a zip and upload it to itch! If you choose web when it gets upload you will have a check box you can choose to embed it to the browser
