I love playing games on the Wii U, but I run in to the same problem with every one of them. I find myself looking down at the screen on the GamePad more than up at the beautiful HD visuals on the TV in front of me. I play games on the Wii U as if I'm playing a handheld like the 3DS; head down, shoulders slouched, never looking up. It's a weird sensation, as I always feel like I should be watching the screen, but I'm a creature of habit.
Evidently, Two Tribes has ported its PC puzzle game Rush over to Wii U with me in mind. The entire game focuses solely on the GamePad's screen itself, and utilizes its unique control scheme to that effect as well.
