Show n’ tell is used for showing images of completions and showing levels you made! For example, if you beat a level but don’t have a video, only a screenshot, then that’s show n’ tell, not let’s play. Same with a level you made. If you made a level and have a completion video, put it in show n’ tell.

Lets play is used for videos of level completions. If you beat a level you did not make and have a completion video of such level, then put the video in let’s play!! Remember, if you don’t have a video and just a screenshot, show n’ tell.

hope this helps! Stay peachy!
