Thanks, worked in Edge for me, but doesn't work in Chrome. Sorry, it's annoying. I think the arrow keys may be an issue in Unity's WebGL for Chrome. Maybe the new input system fixes that.
Just an idea, a cool thing you could add is to use the platform effector 2d in Unity to make one way platforms or one way walls. That would a ton of extra puzzle options.
