Movement - W A S D / arrow keys. Battle mode - Throughout the battle, an Undertale style fight opportunity will appear. Press space to begin it, then press space to stop the line to determine the damage being dealt to the Dancing Cat, though if you miss the opportunity (if the bar goes to the end) your attack will miss and do 0 damage to the Dancing Cat. P S - Press h during the intro to activate hard mode though it might take a few tries
The game gets weirder and faster as you go on. Credits to whoever made The Demonic Little Grey Cat theme used in this project
