That’s weird, there is camera shake and bloom, guess they were too mild :/
Did you play the WebGL version? Or the downloaded one?

WebGL (Chrome, 1920x1080). Either it doesn't work in Chrome or it is so minimal that on lower (non-fullscreen) resolutions it just disappears. And I can see the camera shake now, it might be too little an effect to be noticeable to most people. I just assumed it was the camera jutting around do to the mouse being moved around to try and attack more enemies.
