All Star by Smash Mouth led me to you, but either way, here's the controls: Left and right arrow keys to rotate the pic. WASD to move the pic. Z and X to hide and show a variable. Cats and rocks being related to each other confirmed /j "/j" is a tone indicator, and "/j" means that it's a joke. Having the controls be in the instructions or somewhere where the user doesn't have to see inside is recommended.
Thanks to kinda_dumb for the original project Untitled-2. You may have a goal when setting the account up, but you are actually kinda smart by taking a part of some song lyrics by either pure accident or intention, just make sure you don't make too many accounts and stick to below 3 accounts.
