Use money to buy tables and cards . To open the shops , press and hold the corresponding numbers , then press the letter of the object you want to buy . Tables increase your card capacity ( how many cards you can have (better cards need more capacity)) , and cards increase your money per second ( how much money you get every second ) . The more expensive the object , the better it is , giving more money or capacity .
Beta : New cards , tables and an intro . Alpha : Tutorial with basic variables . Credit to @intro_makr for the intro (remixed by me).
