However, due to the cancellation of the project, version 4.0 was unfinished and, as such, contains some bugs and graphical glitches, from minor to major, which under certain circumstances may interfere with the gameplay. In the new version of the game, Tails and Knuckles were added as playable characters, and the graphics of some zones were also changed.
