Arrow keys. This is the second in a 6 part platformer series, "The Colorless World" by meh. Check out the official studio for "The Colorless World" here: https://scratch.mit.edu/studios/6017503/
IF you came here to rant about how the 1st is a copy of a project, YES, it was inspired by "Red a platformer" ( https://scratch.mit.edu/projects/287936516/ ) by @Zianchen2 but NO, it was not a copy of "Red a platformer" by @Zianchen2
