Hi! First of all, congrats that you managed to make your first game! I'm sure you're already aware of the issues, but because of the physics i'm not really able to play your game. It looks interesting tho.
Another technical thing: 
Now i can't click on the blue button, so i can never play in fullscreen. What i do when making a WebGL build, i leave all the settings like they are (except disabling compression), and on itch.io i click "click to launch in fullscreen".
I hope the feedback helped you, keep making games and they will become better and better. It would be cool if you could check out my submission too. Thanks! :)
