Thanks for playing! :)
The screen shake is something everyone is complaining about. I had to reduce it once - and I reduced it MUCH - and what you see know is the lessened version, still everyone complaining. :D
I'm not saying this as a negative thing tho, it's good to have feedback.
I think the best option would be a screenshake slider - making the current value the maximum - / checkbox to customize it or turn it off optionally. After the jam ends I'll probably add a slider/checkbox pair for that.
About the HP I might increase it to the 1.5 of the current value but I'm not sure yet...I spent some time balancing it, cause I want to find a spot between "not easy, not too hard" and "Alf-F4" where it's challenging but not ridicoulously challenging to reach a good highscore.
