punch the cat with your left and right arrow keys. When you kill a cat, you will gain money. Use your money to upgrade your strength, cooldown, and money per kill. The cats get progressively stronger each time you kill them, so make sure you can keep up. Rebirth to reset all progress, but multiply your strength and money per kill! You also have a 0.1% chance to land a critical hit every time you punch! critical hits do 100x damage and increase your rebirth meter by 100 rather than just 1! also if you're on mobile, just click the fists to punch.
this came out on Halloween so... happy Halloween I guess. this game is 100% complete and ready to play, but I might add small updates later. give me update suggestions in the comments.
