The game looks stunning! The audio is nice and cozy as well (although I can share a few FMOD tips).
But I got super screen-sick because of the odd camera shake. Please turn that into a setting that i can turn off!!!
I LOVE the godray particles. To whoever did them, are these just circle sprites that get smaller? I'd be interested to know.
Regarding FMOD:
1) you are supposed to attribute FMOD. Technically the game is against their TOS. See FMOD Attribution. Since you are using Unity's startup logo (which you can turn off nowadays btw!) you can just include that image in the splash array.
2) when you change to a new tab, FMOD gets stuck in a bad loop. My workaround is this method that you can put into any manager mono behaviour:
private void OnApplicationFocus(bool hasFocus)
{
if (hasFocus) RuntimeManager.CoreSystem.mixerResume();
else RuntimeManager.CoreSystem.mixerSuspend();
}
