This. game. is. pefect. it is one of my 3 favourite games although,i wanna guide the new players. 1st advice: don't do anything with the regen. regeneration might sound cool,but it is the worst stat. never use the orange cat and never upgrade regen. 2nd advice: always upgrade hp and damage. those are the 2 best stats. (damage is the best). 3rd advice: don't underestimate speed and dodge. these 2 mfs can save your ahh a lot of times. even though they're not as good as damage and health. and also: the best cat is the white one and the best stat in the game is damage,if you're interested. so go on,play this game,experience everything,and do challenges! this game is the love of my life. bye.
