Idk I keep reading about it but I'm unsure of if there is any or where to find it 

Right on the store page :P

Cheat codes:

Go in the classroom and input the following codes (there is no UI, you will here a moan if the code worked). Arrows work instead of WASD. For mobile, swipe the screen (W = up, A = left, S = down, D = right)

    WWSSA to gain Lewd Arcana

    ASSWW to gain lewd blooms

    DADDD to unlock all the combat gallery

    DSASS to unlock all items

    ASDWW to upgrade all currently unlocked items

Cheat codes don't work
