The newest version of the boss hub room has now been released ¤cough¤ 6 months later ¤cough¤ with almost all bugs now fixed with some leftovers that will be fixed silently within the next 2 days. Sadly it's almost impossible for me to add a way to identify each door so you can tell which boss is which so in the meantime here's a handy reference image.

How-To:

1. Open the zip file that can be found in resources.
2. Take the two folders inside and extract them anywhere, like your desktop.
3. PROBABLY A GOOD IDEA TO BACK UP YOUR ENTIRE TITAN SOULS FOLDER. <3
4. Put the contents of these folders into the corresponding folders in your Titan Souls folder. DO NOT PUT THEM INTO A ZIP FOLDER You should be good to go. ¤IN THE EVENT YOU WANT TO REVERT ANY CHANGES EITHER VALIDATE GAME FILES ON STEAM OR DELETE EVERYTHING AND USE YOUR BACKUPS. (I SUGGEST STEAM VALIDATION FIRST)¤

The only known bug is that Eyecube will not work AT ALL.Therefore I silently made Eyecube's door lead to the double eyecube room. ¤If the game is crashing try to remove the sound file, apparently it causes issues with some people¤
