The only thing that the game doesn't teach you to do is gather coins. Press c to do this. Coins currently have no function, but they will one day :D Save your game with the save button, then just copy the code ^ - ^ To load data, simply answer yes to the "do you have any data to load?" and paste your code.
There is a glitch where the ball will appear after you close the ball game. Simply open up the game again and close it, and the ball should disappear. This happens when you catch the ball as you're closing the game, and the game thinks you're still playing. Sprites from the cat game Neko Atsume (which I'm currently obsessed with). Coding is all me. Changelog: v0.1 - Base game created. v0.2 - Added coins. v0.3 - Changed the sprites for the food and ball and changed the time it takes for the cat to return from collecting. v0.4 - Added the high score. v0.5 - Release.
