Thank you so much for playing and for your feedback!
I agree with you on all three counts: jump, camera shake, and and auto-restart.
We did want the cubes to feel weighty, which is why the camera shake can be heavy if you drop from a larger distance. The exception is the large camera shake on starting a level, which is a bug that will be fixed once the jam is over. Can you elaborate on what changes you would like to see in the camera shake - is it too long, too strong, too frequent? Any specific cases where the camera shake messes up for you? I agree with you, I just want to be able to have more details about it.
Thank you for the response!
