Rewritten the pulling system - added a separate guaranteeing function, eliminating the bug, where the game would count common pulls while trying to find an uncommon or rarer card.
Began the implementation of save system, allowing you to keep your Kurobis between sessions.
Rewritten the game data management - now all data is stored as an Object
Adjusted card rarities, making the infamous 9 blue and 1 yellow pulls more frequent.
