how do I transform a game in construct to itch.io?

im pretty sure you mean exporting the game. look up a tut on how to export a game in construct

Hi wich software do you use to creat your Game ?

Download the program 7-zip.

  Export the project from Construst to a "New Folder" on ur Desktop

 Then use that file on ur Desktop to make a  .7z file using the 7-zip program.

 Then add the .7z file you just made back into the "New folder".   

With the .7z file inside of the "New Folder" on the desktop, Make a .zip file using the 7-zip program

Then upload that .zip folder with the .7z file in it to ur itch.io page

 .7z file + .zip file = Upload
