Every second map had purple background, I think it is because a texture issue. Why did I keep playing? Because that black hole effect is so impressive, I couldn't stop staring at it!!!!
Hmm thats very weird, it seems to work for everyone else. It looks like its just the skybox bugging out. Maybe try a different browser?
Edit: sorry about that, it doesnt work for me either 😅 it looked fine during testing but i guess it just bugs out on the build version
