*MAJOR CHANGE*
I have now made this mod MTS compatible. As such, this mod will now move to the Steam Workshop. However, I will still be uploading optional files that aim to change the assets Darkglade used in his Wild Card mod (my own preference, not downloading this will not affect the original style of my mod). 
Link to my mod in Steam Workshop: (https://steamcommunity.com/sharedfiles/filedetails/?id=2169873803)


Joker faces his biggest challenge yet.
Without the Phantom Thieves by his side, Joker needs to use the power of the Wild Card to steal the spire and end the loop once and for all.

Hi! This mod is inspired by a mod from the Steam Community Workshop called The Wild Card by Darkglade (https://steamcommunity.com/sharedfiles/filedetails/?id=1817128315)

This mod aims to make the mod much more immersive by replacing the Music, SFX and UI of Slay the Spire with Persona 5.
This mod is still WIP and there will be more to come when I have the time.


Below is how to install the optional changes. I don't know how to program so I opt to manually change Darkglade's .jar file.
*PLEASE BACKUP THE .jar FILE BEFORE DOING THE MODIFICATION*

INSTALLATION

1. Go to your Steamapps folder and locate the workshop folder

2. Follow this File path until you find the WildCard.jar file. \steamapps\workshop\content\646570\1817128315

3. Extract the optional.zip anywhere in your desktop (easily accesible). Open the WildCard.jar file via 7-zip (or any zip opening program) then Drag and Drop theWildCardResource folder to the base directory of the just opened .jar file

4. Enjoy the Steal the Spire Experience!

THINGS TO DO

1.Fix the looping issues. The music is complete but suffers from looping issues
2. If I find better SFX for certain SFX, then I'll replace it
3. Modify the UI to make it look completely like Persona 5 (Almost Done)
4. Learn how to make it use Mod loader so that my Mod does not modify the game file completely.   *DONE*
5. Add a ending comic for Joker after ACT 4 *DONE*

 If you have any suggestions, then I would gladly hear it!
