Okay, I noticed one bug on the tablet (and also confirmed it on my phone as well)
After a "Game Over", if you go into settings and change the ambient light level, the first time it will work as expected, also the second and third times. However on the FOURTH and subsequent attempts to change the ambient light level, the slider will have no more effect until the app is closed and restarted.
I can reproduce this every time.
(Yes, I discovered this because I was playing with the slider and laughing like a mad scientist.
