Note: I cannot provide all of the information to complete a lot of data in this article, I will leave notes where stuff needs to be added.

Chao World is a fangame series by Lionsoft Amatorial Development. The games are Mario-style platformers, although with one small twist. Many levels require you to use Cheese's ability to shoot some collectable items out of his trumpet. The fruits can break crates, melt ice blocks, or do other actions based on what item you use. All of the items can destroy enemies.

Games in Series

Chao World/DX

These are the first games in the Chao World series. The original version was released in 2003, and the updated DX version was released in 2004. Both games have 6 Rounds. Note: Please add round names. The first 5 Rounds have 5 levels, and the last Round has 3. In these games, 3 "trumpet items" are available. The Normal Fruit, which looks somewhat like a mango, can destroy crates. The Fire Fruit, which looks like a pink flower as a item, but turns into a fireball when collected, can melt ice. The Ice Fruit, which looks like a blue flower as a item, can freeze crates and extinguish fires.

Chao World DX improves on Chao World by allowing you to save whenever you wish (Chao World only allowed you to save at the beginning of each Round), adding mini-games (Chao World had none), allowing you to start at any level you have cleared (Chao World only let you start at the beginning of the Round you had saved on), and a preview of Chao World 2: Learn to Fly. However, it lost Chao World's "Round title-cards" which appeared at the beginning of a Round. They displayed the Round number, the Round's name, and instructed you how to save and how to go from the title-card to the first level of the Round. They were removed, presumably because of the different save method Chao World DX uses.

In a way, the games' story is the reverse of Cream's story in Sonic Heroes. In Heroes, Cream is rescuing a Chao, while in Chao World/DX, a Chao is rescuing Cream.

The game has one glitch. Holding X, the jump key, allows the player to multi-jump until the key is released or Cheese dies.
