Editing -sirius- (section)

===Overview===
-sirius- mainly revolves around its effects and its incredibly famous boss fight. The player must first avoid giant spikes in a red area, then enter a blue-and-green area where they become a ball. The gameplay in this part mainly consists of 2.0 elements, such as teleport portals and green orbs. Afterwards, the player must avoid parallax cubes as a ship. Then the level and the music suddenly speed up, and the player is confronted with an automatic black-and-white section.

Next is a warning text, followed by the start of the boss fight. In this first phase, two bosses shoot at the player (now as a wave), as well as giant and large spikes that are also trying to hit the player. The pattern of the spikes changes every time. Afterwards, in the second phase, only one of the bosses stays and shoots laser beams (accompanied by the previously encountered spikes) at the player. Then, in the third phase, the player becomes a robot, and only one boss appears. The boss throws multiple large, deadly purple orbs at the player; however, the player must also know where to go, as there are plenty of platforms that create multiple paths, and not all of them lead to victory. Finally, in the fourth and final phase, the player must avoid laser beams coming from the boss once again, while the deadly circles are still being thrown at the player.

When beating this phase, the text 'Clear!!!' appears, and the boss disintegrates. The level fades to white, and the player can hit the end wall to complete the level.
