Do you have unlocked the first activity in the Shop for 1 dice?
Oh that's what the dice are for? My mind didn't correlate dice to locks
I'm sorry, I've changed things in the meantime. This is rather one of my first published works.
The dice comes from the fact that in the game “Nekomata” she also uses them as a kind of “currency”, and I stayed with that.
Have Fun :)
