Arrow keys. Till the FNF Wiki uploads the new Majin Background, we'll have the outdated Majins in the back. Sorry.
Credits to @Wario1027 for the original project, all I did was edit the sprites' movement places. (For example, the left sprite was kinda to the right, so I had to fix that.) Update Log: Dec. 06, 2021: Made Majin wait .2 seconds before switching to his idle animation.
