(MY FIRST DECENT GAME)Use arrow keys to move space-bar to shoot(only shoots to the right side) walk around as inkling boy(he appears at the bottom so just press the up arrow key to get him on ground. Collect the zapfish thingies (if they are below ground where you can't get them press A and they will relocate) Soon a boss will pop up. Hit it with paint 15 times and you win.
Thank you to Nintendo for making a great game. DON'T FORGET TO CHECK OUT MY OTHER GAMES AND LIKE THEM!
