The environment is great. I wonder where do these donuts came from? Maybe a wormhole brought them from a sugary planet where donuts serve as space ships?
As a developer feedback: Maybe add a sensitivity for mouse in settings, because WebGL doesn't read mouse input in the way that Unity Editor does. And also, your UI is build in a way that hides your health on the smaller in page resolution. Maybe anchor it to the bottom left so that it can move when the window is resized(like in the small not full screen version).
