If you made your game in Unity and uploaded it to itch.io, you can easily upload it as a WebGL. This is very useful since most people don't like to put the effort into downloading your game just to give a vote. Here's what you should do: 1. go to File > Build Settings... 2. select WebGL under Build Platforms and press 'Switch Platform'. 3. now go and compile your game (in a seperate folder!). 4. You should now have 2 folders and a html file called 'index'. Copy all of those into a zipped folder. 5. upload the zipped folder to itch.io, set the game type to 'HTML' and check 'This file will be played in the browser'. 6. DONE! you should now see a "Run Game" button on your game page. If you want fullscreen mode, there's an option in the page settings for that as well. If you don't see the button, but an error instead, make sure that the index.html file is not contained in a subfolder inside of the zipfile.

See how much faster you can load up the game from nothing! click the link, Run game and done!
