Use arrow keys to move the cat. Space To Jump. Q to grow the player, and E to shrink it. HAVE FUN! There are also pro tips you have to learn, but I would not tell all of them.
P.S: The Y scroll doesn't work on my project, because a cat could easily go away from the level. 100% by me with three sprites (bananas included for the SDS Banana Studio) To fix the "stuck" glitch, go inside the project. Change the player's y position to -50 (minus fifty), and shrink to less than a hundred, but more than twenty-five.
