"Cardboard it's 180°" : it's about 10-15 degrees actually, keeping the player focused on the target character, just offering that extra stereo feel of immersion. It's tracking phone's magnetometer and accelerometer sensors (mostly rotation, no position tracking).
- PC-VR and Cardboard would currently work the same, there's no special system implemented. However the PC-VR isn't truthfully tested, and might not perform as expected in some cases.
- "toy syncing for this as for the game to control the toy" yes it is enabled, just make sure to follow the setup steps found in help section of the toy connection menu (the toy requires to activate game mode for providing an interaction IP)
- "Couldn't you also set the reverse, for the toy to control the game? That'd be pretty amazing if possible" : yes, it is possible, and that was part of my goal, yet i was unable to implement such a feature (the basic feedback required some custom implementation extracted from several demo projects provided by the product's dev team, yet for this i couldn't find any solid implementation). Maybe in some future versions, as their API will get more exposure and working projects.
