All are in-game. THIS IS TIMED!
If you do not want the color of the guy flying everywhere, hold "G" when you press the flag that is green. Geometry dash update 2.2 / Subzero inspired this game. Thanks to MDK for the song: "Press Start" (where I got the title from too.) Thanks to F-777 for the song "The Seven seas" Feel free to Remix, just change the levels.
