The art style of Battle Cats is minimalistic but very effective. The sprites are drawn almost exclusively in black and white but every cat and enemy has a personality that shines through in the animation.
The enemy towers are also each meticulously drawn, the whole package looks like it could be hand painted and hung on a wall.
Completing a level gains experience which can be used to purchase new types of cats, upgrade the ones in your roster (with special forms when fully upgraded), and increase support such as how fast currency is obtained, the total amount that can be held, power and range of your cat cannon (on top of the tower) and how much HP the tower has.
