Hi GiantChickenCreature,
Thank you for playing my game and for the game play video. I'm glad you enjoyed playing my game and really like the art style. Also, you're welcome. In regards to ending four, when you're in the hide and seek section, and you've pushed the first two numbers, an arrow appears on the right side of the screen. If you hit the right arrow key, or the D key, it'll take you to a new scene. When you move through that area, and collect all the fish food in the last scene of the section, a door will appear on the right. If you go in that door, you'll get ending 4.
