Play the game "Frizzle Fraz 4" by rescuing various multicolored creatures within each level. Advance between levels by collecting a series of keys to unlock a special door. Also avoid any enemies within the level, as they instantly kill the character and use up one of the available lives.
At the start of the game, after choosing a level, a player takes control of a bouncing fuzzy creature controlled using the left arrow key to move it backwards and the right arrow key to move it forward. As the creature is continuously bouncing, there is no control to make it jump. Over the course of each level, touch the various small, colorful creatures to get them to stick to the player character's body. Collect all of the creatures in each level in order to move on to the next level.
Collect a series of keys to unlock the door at the end of each level. Avoid any monsters, as there is no way to defeat them. Use the bouncing of the character to jump onto platforms and over gaps in the floor. Some levels require a player to time the bounding in order to access high areas via moving platforms.
