Update v1.0.1

Instead of wraping around an imaginary 3D cube in the space the asteroids and enemy ships now 'bounce' back when they reach the edege. This makes it easier to chase them as they don't disappear anymore but head towards you instead. This also makes it a bit more dynamic as you have to be more careful so they don't hit you on their way back. • changed the way the asteroid and enemy ship distance is limited • added the option to settings to not have to hold the VR controller button to keep grabbing the Joystick (just press the grab button to grab the joystick, and press grab again to ungrab the joystick) • changed asteroid explosion scaling mode
