Please strongly consider a toggle to 'disable screen shake'. Please!
Alternatively, a screen shake slider with more/less intense settings may be useful.
It is ok if there is some ini file to edit it manually, however in-game GUI method would be preferable.
One minor quibble but the 'theme' of your game's page with the light background makes it very difficult to see hyperlinks since they are white text. I do have a utility to 'invert' the screen on my end so you should not fell 'compelled' to take any action. I just wanted you to be aware of this, that's all.
