Shironeko VR is a nostalgic action RPG for the Samsung Gear VR (reviewed here) in the tradition of SNES-era games such as Secret of Mana. Did I mention it’s free? ^_^
The camera shows a “god’s eye view” and is generally comfortable. Occasionally, the screen scrolls which is mildly nauseating but these are very brief.
Shironeko can be controlled with just the Samsung Gear VR’s touchpad, but it’s very difficult to do so. It really needs a gamepad. Fortunately, even if you don’t have a gamepad, you can use another smartphone or tablet (iOS or Android) as a gamepad using Colopad, a controller app.
As mentioned above, Shironeko is free to download on the Oculus store.
