just press the space bar to change poses btw if you hold down the space bar it kinda looks like a smooth animation and click the green flag if you want to go back to the first pose the number on the top right corner shows the pose that is being shown and yes you can remix this to animate the rig but provide credit in the instructions or notes and credits since apparently for the scratch team, you have to credit in those
the rig was inspired by @KINGSHIRO and @BurgerLettuceMuncher for 2d Roblox rigs can be made in scratch
