First of i love your game! Not enough good things can be said about it!
Unfortunately I have shaky hands so the gyro in the dualshock is way to sensitive, i have tried reducing it fully but then the movement is SO slow! My idea would be to have a signal filtering option to remove "static" from the input.
I have no idea if this is even possible in real time but it would be great for us with tremors and others I am sure
I also have this issue. It makes it nearly impossibly to fine tune anything while dream shaping.
