Controls need work – Biolab Disaster Review

I actually like the feel of the controls here better than the keyboard-based controls on the desktop. Here's the problem: buttons need to highlight when you press them, even if it's subtle. Also, you need to be able to slide from one button to the next. Right now, you have to lift your finger off the button to go to the next. I find myself walking left when I mean to go right because you can't slide your finger between these two buttons.
