Hotfix v0.5.3.1

Thanks to you, we found two showstopper bugs, one of which we introduced with the latest boss update. So, here's a hotfix for undisrupted gameplay. We apologize for the dark magic at work!

[h3]Fixes[/h3]

• Gold Key in E1L02 can't be obtained
  
• Final doors in the sequence at the end of E2L05 won't open
  

Enjoy!
