We've just done a full test of MacOS, Windows and WebGL builds and they all work as expected. No issue with controls. Could you specify the platform you are on and what sort of issue with the control exists so we can look at it? Thanks :D.
I was playing the browser version and my cursor seems to be buggy and going crazy in the x-plane, but everything works smoothly in the y-plane. I hope this is just a problem with my setup.
Seems like a WebGL issue that appears as you said in your setup. If you're willing you may try to download and play it locally, we have availability on all systems :D. And you can give us your full thoughts!
