I was testing my game, and it always gets stuck loading at 100% can I just leave the link to the game in the description?
If your game won’t work with the itch platform, you might want to resolve this by posting a thread in the Community. Someone might be able to help you.
Having visited your profile, I see you work mainly in HTML5 games. IIRC, itch.io just recently changed how web games work on their site, so that may contribute to your problem there. I have some knowledge of HTML5, CSS, and JS, so feel free to share bits of code either here or on Discord if you need help. (I will not develop your game for you, as that wouldn’t be fair to other participants, but I can point you in the right direction so you can code it properly.)
Regardless of whether it will run on itch’s website or not, please make sure you have a downloadable version of your game ready as per the rules of the Game Jam (it’s okay if you cheat a little by making it need a web browser to run, but if you can make it a game without the need for a browser, meaning it runs in its own window, that’d be even better).
You could create a hyperlink document which is executed when you press the “Launch” button in the itch client or when clicked on in the file list. That should instigate the default web browser opening up the HTML5 document.
However, you can make a standalone HTML5 app using some tools on the internet. Here’s an example: https://stackoverflow.com/questions/29686011/how-do-i-convert-web-application-into-desktop-executable#38620323 (The next few answers have some others that might be more your preference.)
