happened to me earlier, when I used Chrome. Tends to be a WebGl issue, I had a whole convo about it in the Zeno discord server.
I don’t know the details of how it works. But I know for a lot of the browser games I had to play them on a different browser, (my case Microsoft Edge worked for me funny enough). Can’t promise that’ll work for you, but trying out a different browser doesn’t hurt. 🙂
