There are 20 frames of this animation, each of which are a different game.
The ones I've personally identified are, in order: 1. Minecraft (Overworld) 2. OMORI (WHITE SPACE) 3. Undertale (Ruins) 4. Yume Nikki (Madotsuki's Room) 5. OFF (Zone 0) 6. The Stanley Parable (Starting Room) 7. According to this post, this is from a freeware Japanese RPG Maker game called "Cell of Empireo." No idea if that's true, or even what the weird skull thing is supposed to be. 8. OneShot (Starting Room) 9. Doki Doki Literature Club (Clubroom)? 10. Professor Layton (The Curious Village) 11. Cuphead (Floral Fury) 12. Spooky's House of Jump Scares (Room: 0) 13. Baldi's Basics (Starting Area) 14. Five Nights at Freddy's (FNAF 1 Security Office) 15. Stardew Valley (Level 1 House) 16. Among Us (Lobby) 17. According to the artist, this is from "Imscared — A Pixelated Nightmare." I'm not sure, but I believe the location is the first level, "The Beginning." 18. Lobotomy Corporation (Containment Unit for Abnormalities) 19. Undertale (Sans Fight) 20. Deltarune (Computer Room)
