I downloaded this game for windows 10 on the itch.io app(my systems are all updated) and it wont even loaded at all when i press launch. it wont loaded when i did the files manually on my computer, and when i put it on steam to launch. does anyone know why it wont work

Why would you want to "launch" it with Steam? Not all apps will run by launching them in the itch app. The app creator has to do some manifest thing or whatever it is called.

If the app does not start when clicking the executeable in the app folder and no error message is given, complain to the app creator. Or sift through the thousands of comments on that game. There are lots of people with different problems when starting the game.
