You control the cat with the up and down arrow keys. Collect the hearts to get 1 more life. Collect the coin for 1 coin and the money bag for 3 coins. If you touch the house or spike, you lose a life. If you have 0 lives, you lose!
Thanks to @2009erChris, who helped me. You can find this game on his scratch account too. Have fun! Juliur
