Thanks for your feedback, awesome to hear that you enjoyed! That's what keeps me on developing games, hearing from people like you that my effort has brought joy for someone. You'll be glad to hear that I have already taken pretty much all of the point you raised into action with my next game :) You can actually turn down the screen shake amount in the settings already. I think the amount of shake is also dependent on the game performance so it might be too much on some systems and better on others.
You just made my day with your encouraging comment! :)
