Downloading Windows version and opening the 2D Shooter.exe file shows 142 errors. Please fix these errors. Also the reason for your WebGL not working might be that you didn't check 'Decompression Fallback' in the Player Settings for WebGL before building or that you might have not changed the 'Kind of Project' in this itch.io project to HTML. If you did that make sure to check this file will be played in the browser for your WebGL.zip file. Btw thank you for reviewing my project (https://fallguy7.itch.io/2d-shooter) and giving positive feedback. I hope this helps you in fixing your WebGL.
Edit: I converted the Windows.7zip to a Windows.zip using CloudConvert and it works now. You may want to upload a .zip file instead of a .7z file, I'm not sure if it's just my computer or this problem is for everyone. Great graphics by the way! Which software did you use for making the new spaceship and the new asteroids?
