Looney Tunes Twouble! is an Action & Adventure game for the Game Boy Color console. The story follows Sylvester the cat as he tries to capture Tweety Bird.
The gameplay alternates between two types of levels: 3D isometric and 2D side-scrolling. In the 3D level, you must navigate Sylvester through various puzzles to find Tweety while avoiding enemies like Hector and Granny. You'll need to collect items, combine them, and use them at the right spot in a room.
Once you've found Tweety, you'll move on to a 2D side-scrolling level where you must chase him while avoiding obstacles that could trip you up. Catching Tweety advances you to the next level, where you'll need to find him again.
