Certast.

Certast is a screamer playable game made on Scratch by a user named 3921-Roblox and published on  March 15th, 2019. The game's developer claims that he will update it again as soon as possible.

In the game, the player interacts with a yellow character named Certast. If the player chooses to play with Certast, the game abruptly fades to black, accompanied by a strange scream. Certast then introduces the player to a game called "The Question of Death." Certast explains that the objective of the game is to answer a series of questions, and when the player answers the final question, the same effect as typing Certast's name occurs. Typing "Certast" as the player's name causes the face to turn red, and a zombie face covered in blood will later appear, along with the same scream from The Maze.
