Same general observation as Donut_Worm; I'm using the Oculus Rift, and it feels incredibly hard to do anything. As if our character was very weak.
On my gameplay, the ringing alarm when time runs out is incredibly loud and annoying. Scores aren't saved if they are under the required threshold.
Hitting but not breaking the triangle in the Ninja mode doesnt provide points, which is frustrating; I managed to hit the required 20 triangles onces, but since I only broke less than half, it didn't count. Now I can understand that not breaking them doesn't yield as much points but it should at least provide something.
