-Fixed a critical bug with the Oculus Rift which caused the display to go black in the prelude level. I'm really sorry about this one, I assumed that everything was good to go on both hardware platforms when I could successfully play in editor on both rift and vive, and tested the final build with the vive, assuming it would be exactly the same on rift. I've since revised my QA process to be more rigorous to avoid future embarrassments.
Fireball spell has been balanced out a bit. I felt it was too over powered and you could just nuke a large region by charging a fireball in both hands for 10 seconds.
-Fireball cooldown has been decreased from 0.5s to 0.3s; You can throw them faster!
-Fireball AOE has been decreased by 50%.
-Fireball max charge has been increased from 10 seconds to 20 seconds, which means they get powerful slower.
-Zombies can explode into gooey bits if you hit them with a powerful fireball. They also have a new impact resistance threshold which decreases as they take more damage, causing them to be more likely to explode when they're near death.
-Fireball impact force has been increased by 25%, causing them to get more explosive. This makes zombies more likely to explode if you hit them with a well placed fireball.
-The fireball flames visual effect threshold has been moved up from 2 damage to 4 damage. This is purely aesthetic, but should help increase performance slightly when you are lobbing lots of fireballs.
