Demo Bug Fixes (Update 0.1.0)

Thanks to the early feedback I was able to fix and tweak some things:

• partyl fixed a problem that occured with low settings that would make everything way too bright. If that happens to you, it will be fixed if you quit and load any scene again. Sorry for the inconvenience.
  
  
• added some stamina earlier on the game. Downgraded the "upgraded running".
  
• "subterrean" levels are now a little brighter.
  
• "subterrean" level creatures now deal more damage.
  
• various environment & props changes.
  

Thanks for your feedback! If you find anything else, please post in the Community Hub.
