Update 0.1

I made a few change following the feedback from the comment section:

• Change the instruction in the description to make the game play more clear
• Speed up the animations to make the game more faster
• Added a switch button to select x1 or x2 speed of the animations
• Adjust the points needed to get "Ks" from 50,000 to 20,000. Old save data are processed to get the earned "Ks"
• The market prices increase in 1Ks with every upgrade (The buy button tooltip text show the price)
• Add a simple animation with the points you get for every card
