Fantastic work and the effect is sublime! Its simply crazy how much you did in 7 days. Curious how you achieved it - with the use of two cameras looking at two different sets, blending based on a noise cutoff texture, and checking with the same noise cutoff texture to see if your character is based on the dungeon or mall? This effect would be fantastic for game with a horror vibe - or maybe a Stranger Things crossover?
I like how killing the enemies cause them to become phone zombies IRL.
