The Austin Chronicle posted an article about Face Kart, here, saying “Turn off the 3D and play the game by tilting the handheld system. Amazingly, the screen tilts as you turn so the game world always looks right-side up. A small detail that makes all the difference.” Some folks have taken this as meaning that Face Kart is not a 3D game or that we encourage players to turn the 3D effect off for some "artistic" reason. This is incorrect.
First off, the stereo 3D effect of the Nintendo 3DS is amazing. It’s magic. I have been lucky enough to spend each day for the past several months ogling at the wonder of its stereo 3D power, and I love it. Oh, and my eyes are still fine btw. :) Face Kart fully supports the 3D effect – and it looks fantastic. However, the stereo 3D effect tends to get displaced when tilting the 3DS unit to the side (like a steering wheel). For this reason, having the 3D effect on while the tilt-steering option is active can make it difficult to view the 3D effect properly if the unit is tilted too far. Therefore, the tilt-steering control option works best with 3D turned off. Tilt-steering is a lot of fun, and it feels great to turn your 3DS like a steering wheel. If you want to fully experience the amazing 3D effect that the game has to offer, you’ll want to stick with the default standard Circle Pad control option instead.
