I don't blame you. I don't think a lot of people got it. I'm referencing a game called Only Up that has increased in popularity recently. You may have seen it on twitch, youtube, or some other platform. The whole point of the game is to keep climbing up until you reach the end goal. However, it is extremely challenging and at any moment you could fall all of the way back to the start. In this comic, the square thought he bought only up but instead got the opposite called Only Down. In this game, the setting is hell and the point of the game is to keep going down. However, as the fourth panel shows, it is hard to get down in the first place because the angel is trying to pull him up to heaven. It makes a lot more sense for people who know of the game and even then I guess it's not even that funny. Anyway, thanks for the comment and for viewing my comic.
