Phaser planes - problems with lagg

I made a game and just titled it phaser planes and it’s very close to done but now I’m having problems with it being slow once you have more than like 8ppl and since I want to be able to have about 40ppl this won’t work so if anyone could help me fix this problem id appreciate it
here’s the project
https://phaser-planes.glitch.me/

Likely Glitch’s container is not powerful enough to host so many people in a game. Sorry about that!

Also, if you want your site to load faster you should be using a hosted and minified version of the phaser javascript file.

ok do you have any recommendations for places i should host it then that doesn’t have that problem?
