D: it won't load, I had the same problem and this is how I fixed:
Open up the game in Unity Editor (like normal)
Then File - Build Settings - Player Settings - Open up the Publishing Settings - Go to Compression Format - Change the format to Disabled
then it should work and load in browsers :) unfortunately I don't think you can re-upload the file now but hopefully you can fix the problem in the future, if you run into it again :D
in the meantime, maybe upload a video with you playing the game, add its link to the game page, and then potentially people can watch the video and rate your game based on that?
